Good Morning n Hapy Thanksgiving Alan. Myself n Bob n Jim have had fun chewing this over but today were gonna chew on some Turkey later. Thanks for the new tidbit of information. Each time you give us some "new facts" to go on that allows us to add to or modify our answers.

If she ONLY heats up when running but NOT otherwise, that lessens to some degree the talk of miswiring as far as a hot battery voltage source being wired/shorted to that Field light switch terminal, cuz if that were the case it should ALWAYS be drawing current. Hmmmmmmmm ??

Soooooooo lets take a look at the differences when running versus not. When running and IFFFFFFFFF the genny has enough Field current??? providing sufficient magentism ??? to produce enough voltage to latch in the Cutout Relay, THEN THE GENNY HAS THE BATTERY PLUS ITSLEF (more ability) WHICH CAN FEED INTO THE FIELD WINDINGS AND LIGTH SWITCH RESISTOR. Without the Cutout Relay being closed, the Field current is more limited to whats being provided by the genny itself WITHOUT the big batterys ability to pump more current through the Fields.

THEREFORE it looks like we all need to take a closer look at Jims proposition which was a partial short somewhere in the Fields might be a contributing factor. At first I considered a short "TO GROUND" which would NOT contribute to high field current, while Jim was considering a "windign to winding" short which could. Myself n I think Bon were suspecting a mis wirign somewhere, which may still be a contributign factor. HECK IF I KNOW

I guess now the critical thing IFFFFF theres a partial "winding to winding" Field short is where its at. Cuzzzzzz if its a certain kind of short the magnetism will be reduced to the point where the Cutout Relay wouldnt ever latch in (so big battery can feed into a short) but if the short were located at a point that still allowed enough magnetism for the relay to latch in yet still have a path up to the switches resistor it could be pumping extra curent through it causing it to glow. Hmmmmmmmmmmmmmmmm ????????

You know theres another posibility that light switch resistor itslef is bad ??????????????? Thats feasible cuz the genny cant have so bad a field short that its not creating sufficient magnetism to latch the relay in and iffffffff its short aint all that bad,,,,,,,,then I dont see it being a cause for enough excess current to overcurrentg the light switch resistor..

I think for now I still wonder about the wiring or the resistor itself being at fault, cuz I dont feel there could be a field "winding to winding" short bad enough to allow BOTH the relay to latch in PLUS decrease the field winding resistance so much the light switch resistor is over current making her glow.

I wonder what the resistance of that light switch resistor is???????? Whether or not the light dimming resistor or it may be cross wired???

I hope Jim n Bob n others toss out more theories here, cuz Im about to run out of smarts lol still thinking more along the lines of a bad switch resistor or miswiring versus a shorted field fer now till we get more info.

God Bless yall n Happy Thanksgiving
