Morning, Jim!
Now I'm confused. Nothing new there, really. And I'm only on my second cup of coffee.
But stuck in the back of my alleged mind is a thread from a few months back where the problem was a fellow losing the ground contact between the switch body and the frame of the tractor. Can't recall what his symptoms were, though, that led us to that solution.
My thinking below was that the lights find ground through their housings, the only choice being whether the current through the switch passed through the light resistor or not.
From that point, I assumed that the problem I referenced had to do with the function of the charging resistor. I don't have a switch laying around just now to open up and go through, but a quick look at a wiring diagram in the parts book doesn't show any direct wire ground connection on the charging circuit. The wire from the field terminal stud on the generator runs to the switch by way of the ammeter.
You're my guru on this stuff, so I expect I'm missing something. How does the charge circuit get back to ground if not though the switch body? Is there a connection through the body of the relay?
