Light Fixture
Can anyone explain this? I had to trouble shoot a 175w 120v metal halide fixture. It worked fine on the work bench with a pig tail to test it but would not fire off when mounted to the building. The only difference in applications was the pig tail didn't have a ground. I isolated the ground at the fixture and now it works fine but I have no ground protection. Any suggestions?

Re: Light FixtureQuote:
None. It was a used fixture a customer wanted installed and it worked fine for a few days with a ground then nothing. Making it work ungrounded was purely accidental. I'm very reluctant to leave it that way and am stumped why the elimination of the ground made it work. |

Re: Light Fixture
Did you check voltages to ground? between hot and neutral, hot and ground and even neutral to ground?
