Update to this post, the engine is now running good, the carb is adjusted and the mechanical governor is working. Now the issue is that it only makes 40v ac L to N, field boost is functioning, but no voltage regulation, resistance across the brushed was around 6 ohm, cleaned slip rings, and now its down around 1 ohm, but still at 40v ac, have checked all the wiring into the vr, all check good, voltage rheostat checks out, no change when turning pots on vr. It seems to need a new vr, the current vr is a part# 62058, which I gather is replaced by the 67680 and a 73249 jumper harness.
Would still be nice to have some wiring information to check this out properly. I can't seem to find any information on this model of generator, or any parts within it. I would appreciate any help you guys can give me. Thank you
Forgot to add that if I jump the positive field lead at the brushes with 12v dc, the output goes up to about 84v ac L to N, wired for 120/240v 1 ph
Is it the model being discussed in this older thread? The owner's gallery of pictures still exists:
