My floor lights were working fine until I decided to "upgrade" to LED lights. The fixtures are wired backward with the positive wire to the fixture and the ground to the center post of the bulb. Not a big deal, but as I was troubleshooting I shorted the wires and now get no lights. I checked the fuse and it was good and the other lights off the same fuse are working. There is also power to the switch as well. Does anyone have any idea where I could be loosing power between switch and the fixture? This could turn int a much larger project than I had planned.

Thanks,

John

I'm guessing you are testing for voltage across the lamp contacts of the fixture. If so, you could have lost your ground connection from the short circuit condition.

Now that you have changed the positive power to the contact pin of the lamp fixture, try measuring from the center contact pin of the fixture to another known good ground. If you get power there, then just provide a new ground wire to the fixture case.

You are correct, I was testing using the fixture as the ground. I will test with a different ground.
