Repairing Light Fixture Electrical Wiring
What to do when a Light Fixture Does Not Work – The feed tested at 120volts the switch and the light tested at 120volts, but when I screw the bulb in the light it doesn’t work
Understanding Light Fixture Electrical Wiring
Lighting Question: I have a 120v feed going to a light, then to the switch, and back to the light.
- I ran new wire to the switch and light.
- The feed tested at 120v the switch and the light tested at 120volt.
- When I screw the bulb in the light it doesn’t work.
- I then wired the same light same bulb and plugged it in to a different outlet and it worked.
- I wired the same light and bub straight into the feed wire and the bulb wouldn’t work.
- I tested the socket and it showed 120v but the bulb wont work.
- I tried new bulb same result.
I am at a loss what could this be?
The Light Fixture Components are:
- One power feed.
- One light fixture.
- One light switch.
- One light bulb.
It should be simple but I’m dumbfounded!

Yup – these are the one’s that make you loose some hair – I know!
Checks for Light Fixture Electrical Wiring
- Wiring connections
- Wire splices
What to do when a Light Fixture Does Not Work
- Make sure you are testing the hot and neutral, not just the hot.
- Lighting socket tangs, or the center contact connection in the light socket, turn off the light switch and pull this metal contact up slightly. sometimes they get bent down and will not make contact.
- The six foot drop test, well maybe not, (but you sure would like to!)
Considerations for the Electrical Troubleshooter
- Plenty of rest.
- Lots of patience.
- A clear mind.
- No yelling kids or yacking spouses near by.
- What ever you do, don’t throw the thing across the room, kick the cat instead. Here’s a Hint:
The problem is staring you right in the face, it always is!

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
