Situation:a common hot wire feeds two two-way light circuits and the circuitry has worked for over ten years, but now if you switch them on, they can only be turned off (or vice versa) at the same switch, not either switch. I have tightened and inspected the feeding at the pair of switches connected to common hot, and everything looks good. I have not examined the far end switch hook ups yet, believing since both circuits "went bad" at the same time, the problem was the common feed.
I have failed the logic problem here. I know the usual two way diagram, and have not checked any continuity of the switch internals...it can't be that tough, but tougher than me! Any suggestions other than getting an professional? Leo
