Went on the hunt for an open neutral. Found 3 of them. 1st was in one of the previously installed (and functioning) fixtures where there was a poor marette job with 3 house wires were crammed in ineffectively, pushing one of the white wires out of the small marette, the 2nd was the same...
OK. I'll check out the other 3 vacant spots where the wires are hanging...and then have a look at how the other 2 previously installed (by PO) fixtures that function are hooked up....hopefully I'll see a white wire that's not connected or something?
Thanks for the tips. I'll let you know...
Thanks for the replies.
Any particular tester you recommend?
"Open neutral"....hmmm. I'll do some research to see what that is.
There is attic space above these lights, so that's helpful.
An "NCVT-1 Voltage Tester" (Klein Tools). Shaped like a thick pen. End goes red to indicate voltage detected. When I turn the light switch on, it indicates voltage (beeps and light goes red) both at the house wires alone and then at the fixture wires and bulb ends with the fixture installed.
It doesn't take much to stump me, but here it is anyway.
Installed a standard 2-bulb (T8 - 32W) fluorescent light fixture (Home Depot) in the garage. Wiring was there hanging from the ceiling, but the previous owner hadn't installed one in that spot (only 2 of the 6 spots have fixtures)...
