I have a double-gang box with two 3-way switches. One controls a switched outlet, and the other controls a ceiling light from a second 3-way switch.
I made notes when I removed the old switches, but somehow lost them before installing the new ones. I usually take pictures too... of course this was the one time I didn't.
The box has three cables entering it:
Two 3-wire cables (black, white, red/pink)
One 2-wire cable (black, white)
I can't inspect the light fixture because it's a hanging light in the middle of a vaulted entryway ceiling, so getting to it would be a major project.
I did inspect the other 3-way switch that controls the same light. It is wired with:
Red (looks pink) on the common screw
Black and white on the traveler screws
I was able to get the switched outlet working, so that switch is finished.
That leaves:
One 2-wire cable
One 3-wire cable (5 wires total) for the remaining light switch.
Here's what's confusing me:
None of the remaining wires show 120V when tested.
The only constant hot in the box is the black wire feeding the outlet switch.
I don't remember that hot wire being pigtailed to feed both switches, although I do remember some screws on the original switches having two wires under them.
Things I've already tried:
- White wires from the 2-wire and 3-wire tied together, black from the 2-wire on the common, and black/red from the 3-wire on the traveler screws.
- Pigtailed the known hot from the working outlet switch over to the light switch common screw, placed black wire from 2 wire and red wire from 3 wire together on one traveler screw, then tested having white wire from 2 wire then with black wire from 3-wire on second traveler screw.
Neither configuration worked.
At this point I'm wondering:
Is there another wiring configuration I'm overlooking?
What additional tests with a multimeter would help identify which cable is line, load, or travelers since I am not getting voltage with wires when testing.
Any help would be appreciated. I'm comfortable replacing switches and have wired several other 3-way circuits successfully, but this one has me stumped because I lost my original notes.
