170VAC coming from my Onan generator
It's a 1995 4000 BGE. I posted earlier but wanted to focus in on this problem. I tested the lead coming into the breaker switch and it was a consistent 170 VAC. What should I check next and h...

Your ohmmeter is playing Three Card Monte with you. The slip ring leads are encased in a nylon sheath then varnish dipped and baked. They would have to touch each other in order to slow low resistance.
Connect two test leads across 12 volts. Connect your ohm meter to generator AC output. Be careful. Start generator. Do you see reasonably steady voltage?
Connect one test lead in series with the probe through the ammeter 10 amperes setting. Be sure the meter is set to amps and the lead is plugged into the right hole.
Any violation of integrity with the windings in the spool or slip lead connection will show up when the rotor is revolving. Engine running. Wild variances will scramble the meter numbers. Drag the points of the probes, wear short sleeves and move slowly when the engine is running.
I'd tell you how to test the voltage regulator with a battery and a VARIAC, but...
