I live in a pretty old condo in MA, and the living room track lighting stopped working. New bulbs didn't help, but the second set of lights on the same outlet worked fine. Replacing the bulbs and cleaning the fixtures didn't help either.
This weekend, I decided it was time to replace the lights, but this is my first electrical DIY project. I pulled down the old lights, hung the new set connected all the wiring, and turned the circuit back on. No dice: same as with the old set, the new ones don't light up.
A voltage tester shows power at the switch (a dimmer), and power throughout the track.
Any ideas why I still don't have any light?
EDIT: I tried with a CFL, rather than LED bulb, and the CFL flashes. Also tried with an incandescent, which didn't turn on at all. Suggestions?
