A research balloon of total mass 330 kg is descending vertically with a downward acceleration of 0.1 m/s2. How much ballast must be thrown from the car to give the balloon an upward acceleration equal to 0.7 m/s2, presuming that the upward lift of the balloon does not change.Physics Problem(Research Balloon)?
Let F be the upward lift..so m*g - F = m*a =%26gt; F = m*g - m*a = m*(g-a) = 330*(9.8-.1) =
F = 3201N
Now we want a to be upward and = 0.7m/s^2 ...so F - m*g = m*a
F = m*(g+a) so m = F/(g+a) = 3201/(9.8+.7) = 305kg
Therefore 330 -305 = 25kg of ballast must be thrown over

Vertical motion with constant acceleration?
A research balloon of total mass 260 kg is descending vertically with a downward acceleration of 3.7 m/s2. How much ballast must be thrown from the car to give the balloon an upward acceleration equal to 1.1 m/s2, presuming that the upward lift of the balloon does not changeVertical motion with constant acceleration?
Let F be the upward lift..so m*g - F = m*a =%26gt; F = m*g - m*a = m*(g-a) = 260*(9.8-3.7) =
F = 1586N
Now we want a to be upward and = 1.1m/s^2 ...so F - m*g = m*a
F = m*(g+a) so m = F/(g+a) = 1586/(9.8+1.1) = 146kg
Therefore 260 -146 = 114kg of ballast must be thrown over
Let F be the upward lift..so m*g - F = m*a =%26gt; F = m*g - m*a = m*(g-a) = 260*(9.8-3.7) =
F = 1586N
Now we want a to be upward and = 1.1m/s^2 ...so F - m*g = m*a
F = m*(g+a) so m = F/(g+a) = 1586/(9.8+1.1) = 146kg
Therefore 260 -146 = 114kg of ballast must be thrown over
H I D headlights color contrast ?
I just bought a set of HID bulbs in a wiring kit from eBay and I need to know if I can change the color contrast to blue purple like 8000k-12000k with a different ballast, or do I have to use the color code on my lights it says it is 35w 6000k color contrast and it's diamond white will I blow them up! just want to see if any one can help me before I order thanks.
dose any one know how this works stuff works?H I D headlights color contrast ?
ballasts are color temperature specific (8000k ballast with 8000k bulb), 6000k is bright white, and 10-12000k is a cool color, but doesn't light very well. honestly, if you're using oem headlights, i would suggest sticking with halogen bulbs, if you go HID in a oem headlight, you will illuminate everything, and not just the road, you will basically just blind oncoming drivers...i have oem headlights and i use %26quot;fake HID%26quot; bulbs, which are colored to 10000k, but are halogen bulbs and still project the light correctly. HID headlight housings are specifically designed to project HID light onto the road.
I got my bulbs from HIDLOOK.COM... they also sell HID kits if you still want to go that route, or you can get super white PIAA bulbs, or even silvania silverstars from walmart...those work very well as well.

I'm replacing an old point type distributor with an HEI Dist.on a 69 Chevy C/10 Truck. How do i wire it in
I need wiring instructions for the new High Energy Ignition distributor. I am installing it into a 1969 Chevy C/10 pickup truck with a 350 Eng. Is there anything i should know about the wiring and my spark plug gap was .035 will i be changing the gap to .040 or .060 and do I need to run my 12 volt power wire through a ballast resistor before I connect it to the distributorI%26039;m replacing an old point type distributor with an HEI Dist.on a 69 Chevy C/10 Truck. How do i wire it in
SIMPLEST option-------%26gt;
use a test light and locate a fuse in the fuse block that is %26quot;Hot%26quot; only when the key is in the %26quot;Run%26quot; and %26quot;Start%26quot; positions. It should not be %26quot;Hot%26quot; in the %26quot;Acc%26quot; position. There used to be two connectors on the old fuse blocks that would work this way.
Run a 12 wire from the terminal (%26quot;Hot%26quot; side of the fuse, not the fused side) to the %26quot;+%26quot; terminal of the HEI dist.
This distributor requires full battery and charging voltage. Use NO resistor.
When the HEI first came out in the early '70s, the plug gap was recommended from .045%26quot; all the way to .80%26quot;, and there were fouling issues. G.M. came out with a TSB to run the plugs at .035%26quot;, and ultimately recommended .045%26quot; for most applications.

If you had an external module cut the power wire for it (It should be the biggest one) and use that to power the dizzy. If you have a tach use the NEG wire from your coil and connect it to the TACH terminal of the HEI.

there should be red and yellow-or red and brown wires goin to your points style seperate coil-on the hei cap it should be marked with 2-3 wire inputs plus your plug that goes from your cap to your distributer-really all you need is the red power wire to go where it says 12v+-dont plug anything into the place marked tach-thats for a tachometer-not another power source-if it has a placed mark ground or 12v- thats where you hook the yellow or brown wire-but most are self grounded and just have a tach and 12v+ input-hope this helps ya-also just have autozone look up the gap on like a 85 chevy truck-these have hei and will give you the proper gap-i think when i changed mine it went up to 43 or 45 gap

Vertical Motion With Constant Acceleration?
A research balloon of total mass 285 kg is descending vertically with a downward acceleration of 2.7 m/s2. How much ballast must be thrown from the car to give the balloon an upward acceleration equal to 4.2 m/s2, presuming that the upward lift of the balloon does not change.Vertical Motion With Constant Acceleration?
Direct answer --%26gt; 102 kg
Second Law
a1 = 2.7 m/s^2
a2 = 4.2 m/s^2
m1 = 285 kg
m2 = 285 kg - x
F = F
m1a1 = m2a2
(285 kg) * (2.7 m/s^2) = (285 - x) * (4.2 m/s^2)
(769.5 N) = (285 - x) * (4.2 m/s^2)
183.2 kg = 285 kg - x
x = 285 kg - 183.2 kg
x = 102 kg
Direct answer --%26gt; 102 kg

How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
asking someone to keep records on bulb changing is sort of too much. They must have only a few fluorescent fixtures. We have about 50 in our rentals and still don't know what the voltage output of a good ballast/fixture should be. There should be some standardization on this, or if its written on the ballast, how is that interpreted?
it seems like 300 volts ac is good, works; while 125 volts ac doesn't work (bad fixture/ballast)?
can anyone confirm specs /suggestions about info on fluorescent 4 ft fixtures?How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
I haven't had the need to try this resource yet, but here is a ballast troubleshooting guide.

G'luck!How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
I've repaired and replaced a lot of florescent bulbs and fixtures in my business and I've developed a procedure that usually works flawlessly. If you have good bulbs and a good ballast, (very, very seldom do I ever encounter a florescent system using starters anymore), it will work. When bulbs get dark on one or both ends and glo reddish orange, or dim white, or just don't lite at all, it's time to replace them, ALL. If you replace the bulbs and they don't light up, then the ballast is no good either. Also, if bulbs in one particular fixture burn out quickly several times in a row, the ballast is usually bad.How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
When you change the fluorescents write the date on the tubes with a sharpie. Also date the ballasts when they are installed. I've worked on the fluorescents for years and trying to test them with a voltmeter is not worthwhile. Replace the tubes when you change the ballasts, if the tube does not work, replace it and then after about 3 times, the ballasts are usually gone also. The new electronic ballasts require that you use the correct tubess. T-8 vs T-12, it is usually marked on the ballast.How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
The specifications printed on the components of the flourescent fixtures only indicates the normal operating parameters on which the components should be operated with and does not indicate its operating status. To check the
operating status of these things, the more logical instrument to use is the ohmeter which should indicate the continuity of the electric current path inside the components. The two prongs at each end of the tube should have continuity; That of the ballast should also be continues. The starter should be open to the ohmeter because it only closes instantaneously at the application of the normal operating voltage through the other two components.How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
As a plant engineer in a jail this is sadly one of my every day jobs so here is my crash course.
When useing a volt meter to test a ballast be sure to read the electrical schematic printed on the ballast and test complete circuts. i had a guy tell me that the voltage on a 120 ballast was 240 volts and it was bad. To trouble shoot place the meter in to voltage at the proper range and hold the black lead to the green wire this is ground. touch the red test lead to the clips. Lets say you have a two light fixture you will have four clips to test two hot two neutral. the hot line is called the UNGROUNDED CONDUCTOR the neutral line is called the GROUNDED CONDUCTOR. These terms are important if you hope to understand electrical troublshooting. With the testlead on the ground screw test all the clips you should find voltage on two and no voltage on two. if you find voltage on the WHITE GROUNDED CONDUCTOR the ballast is bad because the windings or a component is fried.
THE CLIPS:
More than any other component in a fixture this is where the most problems are. Simply replace them when they are broken. When the fixture is disconected from power one should test for contenuity looking for loose wires broken clips ect. Ever change the bulbs and had the ripple running through the bulbs? Change the clips.
When working with electricy please practice proper lock out tag out procedures. the last thing you need is to have the power restored to a device that you are working on unexpectedly causing a fall from a ladder or worse.How can we tell using a voltmeter if fluorescent fixture/ballast/bulb is bad?
the best way to test a fluorescent fixture or bulb is to wire a pigtail to it and plug it in. The only way I know that you can really test one is under load.How to get stains out of comforter share some encouraging words

How do you know if an electrical balast is bad?
I am trying to change change some lights out but they wont come on. The breakers are on, the switch is on and no light is on. So i figure the ballasts are broken or damaged. How can I tell? How do I go about changing them? Getting them fixed?How do you know if an electrical balast is bad?
Assuming that you are trying to replace flourencent lights do they have a starter 9older models do) Ceck to see if you have power coming into the light fixture(from the switch) you can use any cheap detecter just to see if there is electricity. If electricity is present then you can check on the outbound side (to the light) if there is electricity. if not then you have a bad ballast.
To change you need to undo the connection from the switch(turn off switch first) then splice in the wires to the tomestones(where the tube bulb fits) If the light is original there should not be a splice if the ballast has been replaced before then there will be a splice already. The color code should match up it is probably only red blue and green maybe a grew or white. When buying a new ballast make sure that the ballast and bulbs are compatible with each other. some bulbs require a higher start up so the ballast needs to be the correct type.
Check to make sure that the new bulbs you put in are for the starter that you have. That may be the answer now.How do you know if an electrical balast is bad?
if you have power leaving the light switch and getting to the fixture and have new bulb(s) in the fixture then chances are the ballast is bad. If you have a volt meter or multimeter check the voltage at the light socket. Put one test lead on the socket base and the other in the center of the socket. If no voltage is present and you have checked the voltage coming into the fixture and its present there then you have a bad ballast. For High pressure Sodium and metal halide lights changing the ballast is a matter of shutting off the breaker taking the fixture down then take the light covers off and replace ballast.
For flourscent lights I check feed coming into light (ballast) if I have it there, I then check the voltage leaving the ballast. If no voltage is present then my ballast is bad. Shut off the breaker, remove bulbs and cover to flourscent light. Then change ballast.How do you know if an electrical balast is bad?
If you have one light that is working properly, then switch out the bulbs, if a bulb works on one light-it should in another.

Dead ballast?
A florescent fixture has died (someone was working on it before me), I've changed bulbs, I've rewired the balast in several differnt configurations I removed the ceiling board and check the circuit to make sure it was parralled, finally I replaced the whole unit and now it works.
1) the only thing I can think of is the balast %26quot;burning out%26quot;.Can this happen?
2) if so, how can it %26quot;burnout%26quot; if a balast has no moving parts?
3) are balast and transformers the same thing?but on a different scale?Dead ballast?
yes they burn outDead ballast?
Yes the ballast can burn out and you can go to a hardware store, LOwes, Home Depot and get another one. Make sure you take the information off of the one you haveDead ballast?
Yes a ballast can and does burn out. The fact that it has no moving parts has nothing to do with it. Heat does. A ballast is little moe than a transforner inside a heat sheild ( all the black tar looking stuff ). The ballast can be replaced but usually it is about as cheap to do what you did, replace it.Dead ballast?
It can burn out, the winding wires that make up the transformer are coated with shellac as an insulator which deteriorates over time. The humming sound is caused by vibration (eddy currents) of the wires in the air spaces caused by the deterioration of the insulating shellac.Dead ballast?
1. yes
2. break down of the insulation between the windings.
3. see link for long explanation.Dead ballast?
1) Ballasts can and do burn out, it's no rarity. I've seen a two lamp fixture wherein only one lamp operates because the ballast failed internally for one lamp.
2) It is a transformer that gives the lamp tube the high voltage required to ionize the gas within the tube and cause the gas to flouresce and put out usable light.
3) Refer to number 2.Dead ballast?
1- A ballast is a form of transformer that changes 120 volts AC to
a higher voltage (many different ones work to fire up 1 bulb or 2 bulbs and so on.
2- A fluorescent tube is a gas filled tube of glass with a coating of a powder which aids in the emmission of light when a high voltage is applied to the tube. (Some for example need 440 volts to fire up the tube) It's been a long time since I got into the technical workings.
3- A transformer is made up of 2 sets (or more) of windings that either step up or down an applied voltage.
Such as 120 Volts to 240, 120 to 12 volts (doorbell), some have several different outputs like 6, 12,24 and 48 volts from 1 input voltage. All of these windings are very close together and when operating can get quite warm. After a long time the insulation finally breaks down and short out, get to hot and eventually burn out.
A fluorescent ballast is very much the same and will break down over time.
4- Last but not least, if my memory serves me a simple 1-tube 40 watt ballast has two yellow wires, one black wire and one white wire. (for a two pin twist in bulb) they shouldn't be mixed up.
I used to turn off the power, remove the cover, clip all the wires close to the ballast, remove it, get a replacement and splice the 2 yelows, 1 black and 1 white each back to the same color. They should not be mixed (except for the two yellows).
Hope this helps.Dead ballast?

Question regarding force in the vertical direction?
A research balloon of total mass 420 kg is descending vertically with a downward acceleration of 2.8 m/s2. How much ballast must be thrown from the car to give the balloon an upward acceleration equal to 2.3 m/s2, presuming that the upward lift of the balloon does not changeQuestion regarding force in the vertical direction?
net F = m*a = weight + lift
lift = Fnet - Fw
Fl = m*a - m*g = m(a-g) = 420(-2.8 - (-9.8)) = 420*7.0 = 2940 N
the lift remains the same
so we may now calculate the new mass
Fl = m(a-g)
2940 = m(+2.3 - (-9.8)) = m(12.1)
m = 243 kg
original m = new m + ballast dumped
420 = 243 + m
m ballast = 177 kg
net F = m*a = weight + lift
lift = Fnet - Fw
Fl = m*a - m*g = m(a-g) = 420(-2.8 - (-9.8)) = 420*7.0 = 2940 N
the lift remains the same
so we may now calculate the new mass
Fl = m(a-g)
2940 = m(+2.3 - (-9.8)) = m(12.1)
m = 243 kg
original m = new m + ballast dumped
420 = 243 + m
m ballast = 177 kg
Sailing boat problem?
Hi.I am getting an old Kelt 7.60 DL.The studs are rusty and in poor condition.Need to disconnect ballast from the hull to change studs on.Can I do work my self?What I have to do?How much will cost me?ThanksSailing boat problem?
Are you in the USA, UK, or France?
Don't see too many of those boats here in the USA...
Anyway... on to your question...
I build boats, and what you're asking is a pretty serious question. Unless you really know what
you're messing with - I would have a professional do it.
Here in the states, we just had some University Students and two Instructors take a vessel out into the Gulf of Mexico, and one of the Instructors drowned when the keel feel off the bottom of the boat. The vessel filled with water so fast, he couldn't get out of the cabin... Turns out, they had worked on the keel's repair just weeks earlier.
I can't even start to give you an acurate estimate of what it might cost to have it repaired, as too many factors are in play... (As with most things %26quot;boats and boating%26quot; - one thing always leads to another... )
One thing for sure however... you don't want it to cost someone's life. So... my suggestion is, that you play it well on the safe side.
Happy and Safe Boating!
JohnSailing boat problem?
I would have serious misgivings about the overall condition. When studs corrode the oxidation process has a tendency to migrate into surrounding strata. In a wooden boat it's called 'fastener rot'. If the Keel bolts have gone this far I would wonder what else is compromised. I would strongly suggest you engage a professional surveyor to evaluate the entire hull and all rigging integrity. The last thing you want is to but problems.
Good Luck!

A hot-air balloon of mass M is descending vertically with downward acceleration a...?
How much mass must be thrown out to give the balloon an upward acceleration a (same magnitude but opposite direction)? Assume that the upward force from the air (the lift) does not change because of the mass (the ballast) that is lost.A hot-air balloon of mass M is descending vertically with downward acceleration a...?
Free body diagram, balloon going down (-):
Sum of forces: L - W
F = m * a
L - W = M * (-a); W = M * g
solve for Lift, L
L = M * (g - a)
Free body diagram, balloon going up (+):
Sum of forces: L - W
F = m * a
Let %26quot;m%26quot; be the new mass of the balloon system
L - W = m * a; W = m * g
solve for Lift, L
L = m * (g + a)
Lift is constant, so set both L's equal:
M * (g - a) = m * (g + a); solve for new mass %26quot;m%26quot;
m = [ (g - a) / (g + a) ] * M; the problem asks for the mass/ballast thrown out, so this is just
ballast = M - m = M - [ (g - a) / (g + a) ] * M, or
ballast = {1 - [ (g - a) / (g + a) ] } * M

Can anyone tell me what is a ballast on a florescent lite & how to locate & fix it?
Ok. I changed the bulbs, didn't help. One tube flickers about half lit, the other not at all. I was told the problem is probably the ballast. I'd prefer to fix it myself rather than whine to some man to feel sorry for me. Thanks.Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
Hi, and good for you! I changed mine by myself.The thing is,yours might or might not take a ballast. Your might use starters,and they look like little beer cans about one inch tall. First thing to do, if you can not unplug it, is buy an electrical tester. They are only about four dollars,so don't let anyone talk you into something more expensive,you don't need it. Always test to see current is off,even if you cut all the power off to the house!Test it first! Then you can take the bottom panel off(facing you) and see if it has a ballast. It would be in the middle,with wires connecting to it. It's black, and very,very heavy. I marked my wires when I took them off,with masking tape.Kind of a map, so I could remember how to put them back on, That might seem silly,but I know me,and I didn't want any wiring mistakes and a fire. Next, take it with you for a new one. Their very hard to get the right one, the new ones go by , watts, how many tubes in the light, how long the tubes are,all that stuff. You might need to ask,I did. Than just put it back in the way it came out.Also,when you turn off the breaker, tape the door to the box closed with a sign on the outside of it saying your working on it. Just to be safe,and only use a wooden ladder and wear rubber tennis shoes.1 = BE SAFE! Bye P.S. don't take someone elses advice on what a ballast looks like,those are starters,and quite different!Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
The ballast in most florescent lights look like a small silver device that is plugged into the unit by twisting it to one side. They're tube shaped, about and inch long, and 1 inch around and almost always silver in color. If you can locate this device in your fixture twist it to the right or left to remove it and take it to the hardware store to make sure you get the right replacement part. Good luck.

Why replace the ballast??
Replace the whole light fixture. You can buy a new one at Wal Mart for less than the cost of the ballast.
But if you really want to change the ballast follow these steps. %26lt;%26lt;%26lt;%26lt;%26lt;DANGER%26gt;%26gt;%26gt;%26gt;%26gt;%26gt; BUT BE CAREFUL you are dealing with electricity that can hurt or KILL you... MAKE sure there is no POWER to the fixture when you begin working on it...
1). Find the circuit breaker for the light and turn it off. You can leave the light on and flip breakers until the light goes out. Measure the voltage to make sure it is off. You will be measuring VAC which is Volts AC with a voltmeter. Yes a cheapy meter will work. If you see anything over 1 volt you have not disconnected power from the fixture.
2) Take down the fixture and you will see a black %26quot;box' looking thing inside the light with wires coming out of it. (YES its heavy) That is the ballast. Write down the part number of the bad ballast and find a replacement part. If you cannot find a replacement part then back to the top and replace the fixture...
3) OK ..Now you have the new replacement in HAND....Simply remove the old one (Sometimes you can replace the ballast without taking down the fixture depends on size and location.) but it is usually safer to replace it on the ground.
4) With the replacement ballast in hand note the wiring and replace same using wire nuts and black electricians tape to insure the wire nuts don't come loose....
5). Try the light on the ground and if it works rehang the light...Walla you are done....
Back to the above - It is easier and cheaper to replace the fixture. Less than 10 bucks for a whole new light including bulbs... Good LuckCan anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
These others are telling you what a starter is, not a ballast. The ball est is a heavy long oblong devise inside the unit. Take it apart after disconnecting it. Inside you'll find the ballast, there will be more then several wires to it. Disconnect these.
Take it to Home Depot or Lowes. You will find about 50 different kinds of ballast there, they're not cheap, some are over fifty bucks. Most are in the thirty buck range.
It's that simple, reverse the order of removal and your ready to go.
Mike above is right, why replace the ballest, you can get a cheap light fixture for less then one third the price of the ballest.Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
It's inside the fixture. Turn off the switch or the breaker. Cut the wires close to the ballast so you have some slack to use for the new installation. Take the ballast out and bring it to the hardware store. Get a replacement. There is a diagram on the new ballast that will show you how to wire it in to the fixture. This can be a challenging project for a beginner. Make sure you buy some wire nuts. Follow the diagram exactly and good luck. It's not hard, but it can be confusing for a person who is not familiar with the process.Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
when you get your new ballast make sure you look at the ballast and it will run your bulbs you have there will be numbers on the ballast as well as the bulbs for example
on the bulb you will see something F410/wh42

so when you go buy a new ballast make sure you know what bulbs you have your ballast could be real old and not made any more so you will need something to run you bulbs\

Whine to some man? Then I hope some female electrician comes along to help you out. I won't bother.
Hi, and good for you! I changed mine by myself.The thing is,yours might or might not take a ballast. Your might use starters,and they look like little beer cans about one inch tall. First thing to do, if you can not unplug it, is buy an electrical tester. They are only about four dollars,so don't let anyone talk you into something more expensive,you don't need it. Always test to see current is off,even if you cut all the power off to the house!Test it first! Then you can take the bottom panel off(facing you) and see if it has a ballast. It would be in the middle,with wires connecting to it. It's black, and very,very heavy. I marked my wires when I took them off,with masking tape.Kind of a map, so I could remember how to put them back on, That might seem silly,but I know me,and I didn't want any wiring mistakes and a fire. Next, take it with you for a new one. Their very hard to get the right one, the new ones go by , watts, how many tubes in the light, how long the tubes are,all that stuff. You might need to ask,I did. Than just put it back in the way it came out.Also,when you turn off the breaker, tape the door to the box closed with a sign on the outside of it saying your working on it. Just to be safe,and only use a wooden ladder and wear rubber tennis shoes.1 = BE SAFE! Bye P.S. don't take someone elses advice on what a ballast looks like,those are starters,and quite different!Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
The ballast in most florescent lights look like a small silver device that is plugged into the unit by twisting it to one side. They're tube shaped, about and inch long, and 1 inch around and almost always silver in color. If you can locate this device in your fixture twist it to the right or left to remove it and take it to the hardware store to make sure you get the right replacement part. Good luck.

Why replace the ballast??
Replace the whole light fixture. You can buy a new one at Wal Mart for less than the cost of the ballast.
But if you really want to change the ballast follow these steps. %26lt;%26lt;%26lt;%26lt;%26lt;DANGER%26gt;%26gt;%26gt;%26gt;%26gt;%26gt; BUT BE CAREFUL you are dealing with electricity that can hurt or KILL you... MAKE sure there is no POWER to the fixture when you begin working on it...
1). Find the circuit breaker for the light and turn it off. You can leave the light on and flip breakers until the light goes out. Measure the voltage to make sure it is off. You will be measuring VAC which is Volts AC with a voltmeter. Yes a cheapy meter will work. If you see anything over 1 volt you have not disconnected power from the fixture.
2) Take down the fixture and you will see a black %26quot;box' looking thing inside the light with wires coming out of it. (YES its heavy) That is the ballast. Write down the part number of the bad ballast and find a replacement part. If you cannot find a replacement part then back to the top and replace the fixture...
3) OK ..Now you have the new replacement in HAND....Simply remove the old one (Sometimes you can replace the ballast without taking down the fixture depends on size and location.) but it is usually safer to replace it on the ground.
4) With the replacement ballast in hand note the wiring and replace same using wire nuts and black electricians tape to insure the wire nuts don't come loose....
5). Try the light on the ground and if it works rehang the light...Walla you are done....
Back to the above - It is easier and cheaper to replace the fixture. Less than 10 bucks for a whole new light including bulbs... Good LuckCan anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
These others are telling you what a starter is, not a ballast. The ball est is a heavy long oblong devise inside the unit. Take it apart after disconnecting it. Inside you'll find the ballast, there will be more then several wires to it. Disconnect these.
Take it to Home Depot or Lowes. You will find about 50 different kinds of ballast there, they're not cheap, some are over fifty bucks. Most are in the thirty buck range.
It's that simple, reverse the order of removal and your ready to go.
Mike above is right, why replace the ballest, you can get a cheap light fixture for less then one third the price of the ballest.Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
It's inside the fixture. Turn off the switch or the breaker. Cut the wires close to the ballast so you have some slack to use for the new installation. Take the ballast out and bring it to the hardware store. Get a replacement. There is a diagram on the new ballast that will show you how to wire it in to the fixture. This can be a challenging project for a beginner. Make sure you buy some wire nuts. Follow the diagram exactly and good luck. It's not hard, but it can be confusing for a person who is not familiar with the process.Can anyone tell me what is a ballast on a florescent lite %26amp; how to locate %26amp; fix it?
when you get your new ballast make sure you look at the ballast and it will run your bulbs you have there will be numbers on the ballast as well as the bulbs for example
on the bulb you will see something F410/wh42
not real numbers just made up but simalar will be on both
so when you go buy a new ballast make sure you know what bulbs you have your ballast could be real old and not made any more so you will need something to run you bulbs\

How do I change out the bulbs in my 2004 Lexus LS430?
My Headlights started flickering Christmas eve. I got a few opinions. The conclusion I came up with is that its either the bulb or the ballast. i would like to try the bulb thats working on the non functioning side but do not know how to remove the bulb. Can anyone help?How do I change out the bulbs in my 2004 Lexus LS430?
Open the hood, look over the where the connectors are at. it is usually the one in the middle. you have to twist it counter clock and pull.

How do I change the componets of a f20 type fixture to a more modern one?
I have a old f20 fixture using one ballast per blub. the fixture has 4 blubs. I want to reuse the fixture but change the parts to use the newer more efficient blubs. CanI do this, what parts can you recommend.How do I change the componets of a f20 type fixture to a more modern one?
yes you can change it the parts you will can be pick up at True Value hard ware stores, it is not going to be cheap.How do I change the componets of a f20 type fixture to a more modern one?
you need to get a electron ballast and electron bulbsHow do I change the componets of a f20 type fixture to a more modern one?
It's not likely going to work, and would take to much time, money and effort to do so.
Best bet and in the long run, the cheapest, is to just remove the old fixture and but a new one, to replace it.
That way, you get get a much newer and better looking and performing unit.How do I change the componets of a f20 type fixture to a more modern one?
It could be done but you'll need to find a really good electrician to gut the old fixture of its electronics and put in new components. It will cost more than replacing the whole fixture but if keeping the appearance the same is important to you, go for it.How do I change the componets of a f20 type fixture to a more modern one?
Yep, you can do it.
Any hardware, or building supply store will carry the parts.
You need:
new ballast
wiring, if it doesnt come with the ballast
flourescent bulb sockets (ends) either one pin or two, depending on which kind of bulb you wan to use
new bulbs (I recommend the 'daylight' bulbs, they cost a bit more, but provide a light that is closer to sunshine)
Don't forget to turn off the electric to the light, before working on it...if you dont have a meter, you should get one. Ive seen a lot of homes that run the power to the light first, and then to the switch...so, even with the switch off, you could have a 'hot' wire up there.
I know my local Tru-Valu store carries all of these parts in bins...and you can also pick them up at Lowe's.
Have fun!

How can you tell if a fluorescent light ballast is bad?
I know the obvious %26quot;change the bulb%26quot;. Does anyone know the acceptable output voltage ranges and how to check them safely? I have a lot of fixtures and when doing trouble shooting/maintenance, I always end up with bulbs and ballast of unknown condition.How can you tell if a fluorescent light ballast is bad?
I think the ballast rating is written on the thing itself. They all vary. I know that one is going bad when you notice a more frequent change of bulbs. Eventually a bad ballast will just burn out a brand new set of bulbs. why don't you write down the bulb change date and ballast change date on each fixture? Hope this helps.How can you tell if a fluorescent light ballast is bad?
Have a good look at it they usually show sign's of burning or over heating, if in doubt it's better to change them as they are not easy to check without the proper tools.

RCA DLP Help!?
I have an RCA HD61LPW42 that only starts up if I point a heater where the lamp is located for 2 minutes. I bought this used and have 2 working lamps but not exactly sure if either are original equipment. Could I have a ballast problem?. If so, how hard are ballasts to change and find?. Thanks and happy holidays.RCA DLP Help!?
With RCA's its nots even worth looking at.
Most of teh parts are no longer available, or they are with no ETA.

Have a 1985 Dodge D-100 with 318 and 4 pin ECU. Is 7 volts at + coil post enough to run engine?
With engine not running but switch in run position I have 12 volts at ECU harness 1,2 and correct resistance at distributor pickup and the unit is grounded. With harness attached I have 7 volts at coil positive connection. Disconnecting the single distributor pickup, the starter relay, and the HV coil wire changes nothing. Ballast resistor checks good. No grounded or open wires detected. So, how much voltage is required for operation?Have a 1985 Dodge D-100 with 318 and 4 pin ECU. Is 7 volts at + coil post enough to run engine?

Should I plant my tank now or just add fish for now then plant later when I have more money and motivation?
Fist of all I would like to thank all of you for your helpful answers to my last question.
It is good to hear that I can probably have a planted tank without upgrading my light or filter. After a quick interweb search I found many beautifully planted low tech tanks. I decided that I do want to stick with my original plan of having mostly live bearing fish and a planted tank. The blue gravel and blue light that I have right now seem ascetically incompatible with live plants.
I think that for the most part all I would need to do is swap the gravel for a substrate and swap out the bulb for a different one.
For the substrate I would like to use a mix of inert gravel and eco-complete. Suggestions for good inert black gravel and how to layer it with the substrate would be awesome. Its much cheaper to find the inert gravel at a hardware or garden store right?
My filter is making noise right now that is kinda irritating. It seems to be a problem with the propeller not centering correctly. (it is magnetic) The filter medium is charcoal and that blue fiber.
The noise and the heat from the ballast doesn't seem to be a problem, because I put it on top of a tshirt. How do I know when I need to change the ballast?
Best method for removing scratches? Sandpaper? Cheap products?
All of this is seeming overwhelming right now and what I want are some fish right now so that I can have some gratification now and not after more time and $$$. My plan is to get ten guppies now so I can have something to look at, and then a few weeks or a paycheck or two down the road put in some work to change it from the simple blue tank to a more natural looking tank.
Would this work? I would siphon the water into some ten gallon buckets, add the cheap and effective substrate, swap the light, pull the stand outside and spray paint it black, plant everything and put it all back together.
Sorry I was kinda longwinded and all over the place on this question.
If I put the guppies in now, do I have to trip about getting a thermometer? Do I need a heater this time of year? (I live in LA) The strip on the side is indicating about 72 degrees I think.
If possible, quote prices on any products you are talking about.
Thanks for all the help YAll.Should I plant my tank now or just add fish for now then plant later when I have more money and motivation?
Plant the tank when it's best for you - meaning you have some money to spend on a bunch of plants so you can decorate nicely, and the more plants you add from the start, the more you have to combat algae. The fish will still appreciate a planted setup though, so if you don't already have fake plants, you may as well buy real from the start.
Don't worry about layering your substrate - it just gets messed together anyway all you need to do is mix up your neutral substrate with your enriched substrate. Inert black gravel is available at any fish shop.
If you're doing any spray painting, take the tank elswhere, somewhere well ventilated
A ballast only needs to be changed if it doesn't function any more. You'll want to replace the bulbs every year or so though to keep them fresh because they're just not doing the job as well at half capacity.
From what the strip on the tank says, your water is likely between 70 and 74 (they are not that accurate), which is fine for guppies. The reason you might still want to use a heater is because it prevents temperature fluctuations.
Price quoting is pointless, you need to go cost it out yourself to get any real information. You can save some money if you keep an open mind - I got my ballast and plant bulbs from home depot for much cheaper than the fish store, though it's nothing fancy it does the job just as well.
I don't know what kind of filter you are using, but try to avoid the hanging style - canister filters and sponge filters are much better, especially for planted setups.. You really don't need charcoal in a filter - you can put more sponge in that spot.

Just get the fish for now. Once the tank is well established the the plants have a better chance of doing well. Plant them to early they die and make a mess.Should I plant my tank now or just add fish for now then plant later when I have more money and motivation?
to be honest, the guppies and all fish need plants for hiding away. They need it to feel secure.
so set up the tank with plants first and then get your fish.
fish without plants get stressed and die quickly.
Live bearers MUST have plants to hide in when giving birth and the fry will hide in the plants
to keep safe from prey.
You can do half live and half fake plants or all fake plants, it all just depends on what you like
and your budget.
You need filter and pump
you will also need a heater to keep the tank at a stable temperature, since fish cannot
deal with temperatures going up and down.
The mark you see on the outside of the tank is the room temperature not the water temperature.
Don't forget to cycle the tank before you buy any fish.
Cycling takes 6-8 weeks to complete.Should I plant my tank now or just add fish for now then plant later when I have more money and motivation?
I don`t know much about aquarium plants,but I do know that there are several plants that do not have to be planted in the substrate such as hornwort,try these fishchannel.com and or fosterandsmithaquatics.com.see there plant substrates.
As for the scratches sandpaper well just make more scratches.
Saving the water in buckets is a good idea. 72-75 is just about prefect for guppies.
The blue gravel well be fine as a top layer,but the blue light well not work.

How can I tell if my flourescent light bulb is going out or if it's the fixture itself?
I have two flourescent light fixtures in my kitchen. I changed the bulbs in one last summer but it still flickers (or doesn't come on at all). Now the other fixture is flickering like a strobe light. How do I know if I need to change the bulbs or change the ballast?How can I tell if my flourescent light bulb is going out or if it%26039;s the fixture itself?
There are a few ways to do this. As an electrician, we carry a gas lamp checker that would determine if your bulb is good or not. I'm sure as a homeowner, you don't have one of these.
You can also check the input and output voltage from the ballast. However, I do not recommend this as you will be working with live voltage between 120 volt input and 500 to 5,000 volts output.
Typically, when the bulbs go bad the ends are blackened. However, this is not always the case. Bulbs are cheap ($2.00 each) and I would recommend changing these first. If only 1 bulb is bad, I still recommend changing all bulbs in the fixture.
If this doesn't work, then it is probably the ballast. Turn off the power and open the center cover in your fixture and get the catalog number off of the ballast (do not remove your ballast or touch any of the wiring) and take this to Home Depot or a hardware store and get your replacement ballast. Depending on the type of ballast these vary in price from $12.00 to $25.00.
Once you have your new ballast, just replace the old ballast one wire at a time. Of course, be sure that the power is off before touching any of the wires. It doesn't hurt to verify that the power is off several times.

Changing the ballast does not mean that you have to change the entire fixture. New ballasts are available at any hardware store, and pretty cheap. I would clean the bulbs and re-install.
If that doesn't work replace the ballast. Your bulbs should be replaced also. They have suffered abuse from the malevolent ballast

How do you know if you have to change a ballast?
I have 3 light fixtures, 2 of which looked like the bulbs were burnt out so when I put in new bulbs and they still didn't work, I learned that's because the ballast needs to be replaced. There is 1 more light fixture that is a two-lamp fixture, and one of the bulbs has burnt out and the other one is still working but the light is very dim. I'm wondering if that fixture needs to get the ballast replaced too because someone told me that if there is light, then the ballast does not need to be replaced.How do you know if you have to change a ballast?
In flourescent fixtures, usually when the ballast is going the lamps flicker - sometimes regularly, sometimes intermittently. Seems as if you just have bad tubes in the fixture. Won't hurt to replace them - and if their light is not up to par, or they flicker, then you know the ballast has to go, too.How do you know if you have to change a ballast?

If your going to replace the ballast in one chances are they are all going, for manufacturers seased to manufacture fluerescent lights with ballasts years ago, because the ballasts leak and they give off a harmful gas, I would look for another fixture without a ballast that would fit there, it will cost you about the same as having the ballasts changed in your old lights and you will be more energy efficient.How do you know if you have to change a ballast?

Everyone Else has covered the ballast troubleshooting thing.
I just wanted to say that if you DO need to replace the ballast. You may want to think about changing the whole fixture as ballast by themselves are 90% of th price of a fixture (unless real decrotive).
to have them shipped is crazy as they weigh so much. most ballast that I have changed have been a real pain and usally invole taking down the fixture any way.

Won't hurt to replace them - and if their light is not up to par, or they flicker, then you know the ballast has to go, too.How do you know if you have to change a ballast?

If your going to replace the ballast in one chances are they are all going, for manufacturers seased to manufacture fluerescent lights with ballasts years ago, because the ballasts leak and they give off a harmful gas, I would look for another fixture without a ballast that would fit there, it will cost you about the same as having the ballasts changed in your old lights and you will be more energy efficient.How do you know if you have to change a ballast?
You have just described the exact senario in which you will need to replace the ballast. Just make sure that you did replace all the bulbs, because the other could be out as well. Hope this helps.How do you know if you have to change a ballast?
Everyone Else has covered the ballast troubleshooting thing.
I just wanted to say that if you DO need to replace the ballast. You may want to think about changing the whole fixture as ballast by themselves are 90% of th price of a fixture (unless real decrotive).
to have them shipped is crazy as they weigh so much. most ballast that I have changed have been a real pain and usally invole taking down the fixture any way.

Is it dangerous to tan when a ballast is out? How do I change the ballast? Tanning bed?
After researching I'm to the conclusion that I have a bad ballast. The tanning bed worked fine 2 days ago.. then I get it in my home and all setup, and 4 bulbs (which work fine when moved around) in a row won't turn on. Well, can I tan in it anyways. How do I figure out what ballast I need to order.. and about how much do they cost? and how do I change it? Also.. is there a way to look at it and double-check that that's the problem. eg. when I fuse is blown you can tell.. will there be a visual different between a working ballast and a non-working ballast?Is it dangerous to tan when a ballast is out? How do I change the ballast? Tanning bed?
No light, no tanning.
If it's a 'U.L. listed' unit it will be safe enough to use
with only some of the lamps working, but better to
fix it.
Ballasts do not fail often. I'd suspect something else.
If it's been moved, those lamps may just be loose in their holders.
Try twisting them slightly to re-seat the pins in the holders.
If it's an older unit. there might be little cylindrical 'starters' as well.
Make sure that they're seated in their holders.
Ballasts do not always show exterior signs of failure.
You can look for scorching, that would be one, but it doesn't
always show.
Look carefully for loose connections.
(Power disconnected, not just switched off, while you're 'in there'.)
Unless you're confident of your ability to make safe
wiring connections, I don't recommend that you try
to change a ballast.Is it dangerous to tan when a ballast is out? How do I change the ballast? Tanning bed?

Changing ballast in parallel fluorescent lights?
There are 4 sets of fluorescent light fixtures in a room. I believe they are wired parellel. The lights are old, and a ballast went out in one of them. It was the old kind of ballast where it has one red and one blue wire going to the bulbs. The new ballast has one common red wire for the bulbs and 2 separate blue wires for the bulbs. Redoing the wiring for the new ballast is fairly straightforward.
But the difficult part for me is how to do it parallel. There was a hot %26amp; neutral wire coming to the end of the old light fixture which then fed into the old ballast and also fed to the next set of light fixtures. I'm not sure how to rewire it.
In a nutshell, I've got a hot %26amp; neutral coming in. The black and white wire for the ballast, and a hot and neutral going out. I have the single red wire from the new ballast going to both ends of the 2 bulbs. Both blue wires are connected separetly to the other ends of the bulbs.
How do I connect the remaining 6 wires?Changing ballast in parallel fluorescent lights?
First check to make sure that the ballast that you purchased is appropriate for the bulbs that you will be putting back into the fixture. The old fixture required T-12 bulbs and it sounds like you have an electronic ballast intended for the newer T-8 bulbs.
Once you have the right ballast you will notice that it has a wiring diagram on the ballast. Following the diagram two wires will be intended to be connected to hot and neutral. It may be that the wire that is to be connected to hot and neutral will come from one end of the clips and not from the ball use. When you have the ballast wired into the fixture and you have isolated the two appropriate wires you will simply connect all the blacks together and all the whites together (assuming that all the color designations are consistent and correct.)
You may have to extend some wires within the fixture to do this.

I am electrician with good experience but I don't know How much Should I charge to change a ballast?
Forget time and material. forget what everyone else charges. What are YOUR expenses advertising, labor burden, insurance etc how much do you want to make?

How much will it cost to change a ballast and a bulb?
We very rarely ever replace Ballasts on fluorescent lay-in or surface mounted light fixtures. It's too cost prohibitive, it's cheaper to replace the entire fixture.How much will it cost to change a ballast and a bulb?
about 20 bucks
Don't kill yourself! Turn the power off and test it.How much will it cost to change a ballast and a bulb?
Try replacing the starter first. If there is no starter, replacing a ballast is pretty simple. Just take the fixture apart to reveal the balast, get a similar one to replace it, then just connect the wires the same way.

depending on the light, it mite be easier and better for you to just buy a new one-some bulbs are like over 60-70 dollars-if it is a cheap light then just buy a new one-if it has some value then listen to the guy that told you how above-good luck...How much will it cost to change a ballast and a bulb?

you are all assuming it is fluorescent, which in that case it very well may be cheaper to get a new fixture. but, if it is a metal halide or high pressure sodium it would be cheaper to change the ballast.

How to change a ballast on a fluorescent lighting fixture?
I'm applying for a new job as a maintenance technician at a local college and need to know how to repair and replace ballasts attached to fluorescent lighting fixtures. Generally what are the steps taken to do so and what kind of tools would you use?How to change a ballast on a fluorescent lighting fixture?
Pie mash found a great one for you.
It really is very simple. You just need to make sure the new ballast is the right voltage 120 or 277. But most are dual voltage now. You need to make sure that the ballast you are putting in will do the same light bulbs you have.
If you can not shut the light fixture off, cut the hot wire first. That wire is gonna hurt if you are not careful but the other wires will hurt more.
You can't mess it up if you just wire nut color to color.How to change a ballast on a fluorescent lighting fixture?
I'm not an electrician but the ones I've fixed have been pretty easy. You just need to remove the bulbs and the panel from the fixture. The ballast is a black metal box with wires going in and out. The ballast will be attached in some fashion to the top (ceiling side) of the fixture - may be some type of clip system or screws. With the power off (it's safest to turn it off at the circuit breaker), clip the wires or remove the wire nuts at the splice and remove the ballast from the fixture. Attach the new ballast and re-wire. Just remember how the wires were attached originally and do it the same way - the wire colors may or may not match so make sure you note how they were attached before you remove it. You may need to strip the ends of the wires to splice the wires from the new ballast into the wires from the fixture. You also may need to shorten the wires from the new ballast a little bit so you don't have a bunch of excess wire to deal with - obviously you don't want to cut so much that you can't connect the wires. Twist the ends of the ballast wires to the ends of the correct wires from the fixture in a clockwise direction and screw on a wire nut. Re-attach the panel and replace the bulbs turn the power back on and then turn the light on from the switch to make sure it works. The tools you'll need are a screwdriver (probably Philips head but have a flat head just in case), wire strippers, wire nuts, a flashlight if there's insufficient light in your work area, and possibly electrical tape. You may want to have someone show you how to do it first just to be safe. You are dealing with electricity after all.How to change a ballast on a fluorescent lighting fixture?
Turn the power off to the fixture. Remove the bulbs and locate the ballast. It is important that you use a ballast that is the same as the one you are replacing as they vary according to voltage, bulb size and number and other factors. Make sure the power is off to the fixture then cut the wires leading from the existing ballast. The wires should be color coded. Remove the existing ballast and install the new ballast. Connect the wires from the new ballast following the wiring diagram on the ballast. Most of the time you will be connecting wires of the same color. Replace any components you needed to remove to get to the ballast and reinstall good bulbs. If the existing bulbs are dark on one or both ends, it is a good idea to replace them now. Turn the power back on. Good luck on the new jobHow to change a ballast on a fluorescent lighting fixture?
The first step is to either be truthful with your interviewer and tell them that you know very little about light fixtures: or obtain your electrical license through your state agency and then apply for the job. After that, you need to match the ballast type with the application. T5, T8, or T12. 2, 3, or 4 lamps. 120 or 277 volts. Rapid start, Instant start or programmed start. You also need to make sure that the ballasts you are installing comply with local and national electrical codes and Department of Energy standards currently in place. Do you get my point? To replace the ballast, you need to take into consideration many factors, not just what wires to connect.How to change a ballast on a fluorescent lighting fixture?

How much will a contractor charge to change 2000 fluorescent tubes in a building, wo ballast or disposal costs
I'm doing a report for school and need to know what the labor costs would be. No disposal or ballast change costs. Just 2000 fluorescent T-8 tubes in an office building with regular 9-12 foot ceilings.How much will a contractor charge to change 2000 fluorescent tubes in a building, wo ballast or disposal costs
In my opinion a guy with a step ladder will replace about 15 an hour (assuming reasonable access) = (say) 135 man hours.
Depending on your country you will need to multiply by a labour rate ... in the UK I would allow an all-in rate of around 拢20 per hour (maybe $30 in US as a currency conversion but labour rates may be lower).
Equates to 拢2700 in labour although it depends on whether you are working in premium time etc. I would also allow 拢500 for set-up etc ... overall likely to get costs of c拢3500 LABOUR only.
Be aware that whether or not job is competitively tendered will also affect the costs.
