I just wired up some track lights. Five in a row. And they all work except the last one. I tested it and it has 120 volts I put the light in and it has 120 volts. I took all the lights out of the first 4 and still no good. Could the last one be grounded? But wouldn't that make the first 4 not work as well. Any feedback would be great
Thanks-

Try a new bulb?

Yea I tried a new bulb even put the bulb in another fixture to make sure it worked there still nothing

Look at the little contact points, make sure they are not bent,
Are you installing on track 180 degres out.
Remove a working one, look what side of track single contact is on.
Also compare good and bad one side by side.

Thanks ill give it a shot

The common wire was loose on the previous circuit tthanks
