F96T12 Ballast Changeout
Just lost some hair and made some grays over this ballast change. Customer had a failed magnetic ballast and I ordered in a replacement, and of course, this one is electronic...no problem, right?
I verified the wiring diagram and it was the same as the magnetic, so I added in the quick disconnect, installed it, reassembled and nothing. After several times of doing this, I called tech support on the box. Unbelievable that I'd call support on a ballast change, but I did. They said that the fixture cannot be lamped while energized or it trips the internal-end-of-life switch; turn off the light and turn it back on. So I did, and nothing.
My last resort was to change the ends. They looked good, but apparently they weren't, because that did the trick. I suppose there was a bad connection in an end and possibly that simulated a lamp change and locked out the ballast.
Moral of the story: When a ballast fails on a F96T12HO fixture, buy a complete new fixture and replace the whole thing or scavenge the parts, including the ends.
