OK, if I read your post correctly you're saying you run both routes? One from the generator case field post to the cutout box F terminal, and another wire from the generator field post to the switch? Wouldn't a single wire from the generator field post to the switch be doing the same thing by itself? That is .... position #1, field through the switch resistor to ground for low charge rate, and in position #2, field through to ground directly at the switch for full charge?

To clarify, only a single wire is required - from the generator F post to the light switch field resistor terminal. Nothing is connected to the cutout box F terminal.

So why did they come from factory with the cut-out hooked to the gen field

When no lights were on the tractor, there was no other control for the gen. The cutout had that resistor to ground that allowed the gen to produce just enough that averaged tractor use charged the battery correctly. The third brush allowed a range of farmer selected adjustment to charge more or less. The operator may have had only the mag grounding mechanical pull wire kill switch to control running. Jim
