I started the Coleman Generator problem thread about two weeks ago.
It quit producing power after about 1 hr 15 min.
After dissassembly I found an overheated exciter coil, a defective capacitor
and a burned open foil on the pcb.
I removed the bad 19 turn coil and wound a new one in the stator. I got
a quart of motor varnish at a motor repair shop and revarnished the coil.
I baked the stator in my wifes oven! I varnished and baked the unit twice
just for safety.
(I did note that one of the fiber insulators was not properly placed in the
stator, I think this is where the coil rubbed the stator and shorted,
causing the failure) I replaced the bad capacitor and repaired the open
foil.
This morning I reassembled the unit and fired it up. It works!
I applied a 3300 watt load and it's been running almost 4 hrs at 119.2volts

That's the way it's done! Good job.

Good on you! Repairing the "unreparable" is the ultimate in recycling. The
landfill gets cheated again.
