My VHOs stopped firing yesterday after only a couple of months of service. I fiddled around with the plug a bit and found that the bulbs in the 1 and 2 hole would fire for a second or two, but the bulbs in the 3 and 4 hole wouldn't flicker at all. After a half-dozen power ups/downs, they all finally fired and stayed on.
I assumed that a bulb had gone bad, so I got in tonight and started moving bulbs around to try and figure out which one had gone. I even cycled a couple of good NO bulbs into the mix. But no matter how I moved the bulbs around, the 3 and 4 hole would not fire. I did prove that all of my bulbs would fire (momentarily) in the 1 or 2 hole.
I'm wondering which of the following might be true:
a) I've got a bad bulb or bulbs
b) I've got a bad connection in an endcap somewhere
c) I've got a bad ballast
d) Something else entirely ???
Anyone got any ideas how to troubleshoot this and figure out which of the above I'm up against?
TIA,
Bryan
