Here are a couple of diagrams of how some 3-way switches that I have seen were wired. Take a look at the available wires and see if you think they can be wired to work properly. In both diagrams, each 3-way switch basically has a hot, a neutral and one single wire going up to the light fixture.
3-Way Switch Diagram 1:
In the above diagram I ran up on this situation one time on a service call for a 3-way that wasn’t working right. I have to admit that upon first looking at it I had to scratch me head for a few minutes before I was able to get it working right.
This next diagram was how one was wired that I ran up on that did work and it made me wonder how it could possibly work right. After seeing how they had it wired it made sense then.
3-Way Switch Diagram 2:
I have seen 3-way switches wired about every way possible but these two had to be tops in the unusual department.
