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 119.2 volts. Mike PS. Anybody want to buy a generator? ;-)
