Why did my ballast stopped working?

Why did my ballast stopped working?

A dead fluorescent can be caused by lack of electrical power (tripped breaker or blown fuse), a dead or dying ballast, a dead starter or a dead bulb(s). Check for power first… then the starter (if applicable) and then the bulbs. When all else fails, the ballast should be replaced.

What to do with the yellow wires on a ballast?

1. If you did not remove the baluster, just connect the bulb.
2. The 2 yellow wires go to the white neutral on one side of the fixture.
3. Colors of the wire don’t mater after the hot and neutral go into the fixture.
4. Once you remove the ballasts, the colors of the wires don’t matter.

How do you remove wires from a ballast?

How to Bypass a Ballast

1. Turn off the power. Flipping the light switch to the “off” position does not necessarily end the flow of electricity.
2. Locate your ballast.
3. Cut the hot and neutral wires.
4. Cut the socket lead wires.
5. Remove the ballast.
6. Connect the input wires to the output wires.

Why does my light ballast not turn on?

One clue that your ballast is the reason for a non-working fluorescent light is the light bulbs struggle to turn on. As I said in the intro, we noticed this happening over a 3-4 week period. A good way to check that your ballast is the culprit is to turn on a voltage detector and hold it next to the wires supplying power to the ballast.

What to do if you have a bad HID ballast?

This step will check if you have a bad HID ballast or LED driver. The HID ballasts or LED drivers are the two metal boxes that came with your kit. To perform this test, please swap your HID ballast or LED driver to opposing sides and note what happens to your kit. Swap the HID or LED bulbs to opposing sides.

Do you need to change ballast resistive wire?

If you have a ballast coil installed with a ballast resistive wire or a ceramic block then you can keep the coil as it is, there is no need to change it BUT if you change the coil you do need to match it to a ballast if one is present and not bypassed.

Is there a way to bypass the ballast resistor?

Some customers report that bypassing the ballast resistor by disconnecting the ballast feed wire ( from the starter solenoid or built into the loom) and providing a direct 12 volt feed from the starter solenoid/relay or fuse box to the ignition coil has proved to be a success and has given good results.

What does it mean when a multimeter says ballast is bad?

If the ballast is bad, then the needle won’t move. If you’re using a digital multimeter, often the digital readout will possibly list a “1” when it doesn’t find a measurable resistance.

What’s the best way to fix a light ballast?

This time around I recommend wiring the ground first, then neutral (white wire), and lastly the hot wire (black in color). Twist the wire nut until the connection between the wires from the ceiling and the ballast are secure. Push all the wires back into the junction box as neatly as possible.

How can I tell if my light bulb ballast has bit the dust?

If you’re still unsure your ballast has bit the dust, then you need to get your hands on a brand new bulb. This is a trial and error method. Take out your current bulbs and replace them with the new bulbs. If the bulbs fail to light up, then 9 out of 10 times the ballast is culprit. You could also try using a multimeter set to measure resistance.
