Well, I just took the fan down from the ceiling, and found that the neutral had come loose. So, I ran a new pigtail, and all works fine. I wonder if there would be 120v between the disconnected switch wires now, and if so WHY?
Maybe I've stumbled upon a troubleshooting technique? If you don't find 120v between the switch wires (when d/c from the switch)
, then you know there's a failed neutral?
I don't know, it's just that in the past, when I've disconnected switches, and measured voltage between the two switch wires, I've always read 120v, and I've never undertood why. It seems like all I'm doing is measuring a wire because 2 wires on a switch simply completes the hot leg to the light. ??
