But if the 2 wire is bringing the power in, why is the black from the 3 wire jumping across both switches?
We have already covered this part and that's not how it's wired. . Left switch is first in line, jumper is not on the switched power. The issue is the red wire heading out to the light on the top of the left switch which goes from 36v(off) to 85v(on).
Does les the fact that 85+36 = 121 point to the problem by any chance ?
Just did some reading about phantom voltage and it showing up in underground wiring that is run through conduit. Any sense to that? Or should I just stay the course and look for the box in the am to see if there is a clear answer ?
Doesn't your last picture show 120v on the switch when it is on? If so the problem is beyond the switch as Sparky already said.
Pull all of it and start fresh. You're spending more time troubleshooting it than having it work. Been there before. Who knows how or what they did in those pipes.
