Removing ceiling fans from two rooms in an office and replacing them with LED ceiling lights. Easy. Each room has two wall switches, one makes the fan go, the other the lights. The wiring is white/black to the fan, white/red to the light, common green. Here is what I expected to get when testing: switch #1 ON, you get 120v to white/red switch #2 ON, you get 120v to white/black However, what I found with the meter was: switch #1 ON, you get 120v to white/red switch #2 ON, you get 120v to white/black AND 35v to white/red switch #1 and #2 ON, you get 120v to white/black and white/red switch #1 and #2 OFF, you get zeros everywhere So... where exactly is that rogue 35v coming from? Both rooms had the wiring the same and both had the 35v on the 'off' circuit when one was active and both the light and fan have been working for years AFAIK (wife is just moving into this office this week). Wiring looks original to the building (mid-90s) being covered in over-spray from the original white color the rooms were. I can see some sort of mis-wire giving us 120v on both, but 35v? The fans were not physically hooked up when I was testing, just the multimeter so I'm not even sure what would be stepping down the 120v to 35v. Both rooms were exactly the same, and that 35v was rock steady in both. I disabled switch #2 since it goes nowhere now and I didn't want 35v going to the new LED fixture if someone flipped that second switch. No idea what that would do to the light. But... for the last N years has it been that if someone had the fan running without the light the bulbs were getting 35v (yet not lighting up)?
