Sears 3600 Watt Portable Generator

I don't understand the pictorial diagram, and really cannot read it. But if the schematic (top diagram) is correct, do the stators have continuity?

It appears to me that if one phase of the 120V works, IE the rotor is driving it, then the problem could not be in the rotor or bridge

It almost has to be in the dead stator or connected wiring

I don't know about thermal fuse........those might just be simple splices. If one stator is open, I'd sure as heck open it up, LOL

Thanks again for your help, Del.
All have continuity .5 ohm and none are shorting to ground.
The thermal fuse idea was just a connector wrapped in shrink tube.
Trying to load a larger picture (split into three). Maybe a little easier to see.
Bottom diagram shows the rectifier/dual brush assembly. The red lead off the rectifier was the shorted one.
I think I'm going to try cleaning the commutator(?) rings as one looks much darker than the other. Neither ring is grooved or has much wear at all as this thing has only ran three times since purchased new.
