I doubt this to be relevant to your situation, but I've had a similar problem that I just could not figure out... I suspected a loose solder joint somewhere but I went over every joint and it wasn't that.
Turns out I'd over-tightened the nuts holding one of the pots in and it didn't like it. Loosened the nut on the problem pot and that resolved the issue.
As I said, probably one in a million for that to have been the problem, but it's free and easy to test.
Failing that, I'd suggest finding a multimeter to start testing continuity, while following the wiring diagram, that the good doctor provided above.
