Thanks typerr & sdrtile. We are remote now but came into town for grits a little wifi.
Traced the wiring diagram. Found the circuit breaker in panel above generator. Opened the plastic cover over the lock, looks clean, new. Laid a multimeter over the two limit switches and actuator solenoid. Visual check of wiring under dash leading to rocker switch. All good.
Thanks to junk food with free wifi,
we ordered a a new rocker switch. My best guess at this point. Will be home before us. Going back to the rig in a few and removing a little used rocker switch from something to test my theory. (Well yes, we did order two in case I am true to form and break one)(and yes, I can touch the two switch wires to test theory, but want replacement in hand first. We are already headed home with outside molding held on with Gorilla tape. That's enough baling wire and bubblegum for one trip.)
