Thanks Roger, Ive learned something today yayyyyyyyyyyyyy

My generic Troubleshooting Procedure was written with John Deere tractors in mind that use EITHER the 2 pole (BAT GEN) Cutout Relay and the Light Switch (works same on all brands and as you described, low charge via resistor or high charge dead grounded via the light switch) ORRRRRRRRR the 3 or 4 terminal Voltage Regulator and I knew many IHC were the same.

HOWEVERRRRRRRRR I was well aware of some of the IHC Cutout Relays also having the FLD terminal but thought??? they still werent full fledged Voltage Regulators but Cutout Relays or modified cutout relays ONLY....

BUTTTTT I WAS NOT aware when n where n how they wired actually and was gonna ask Bob M someday. I didnt realize when they were used one didnt use the light switch then ?????? I guess I still dont know if they are alwayssssss in the low charge resistive ground position or how n if they change to the dead ground high charge???? I reckon they could do so sort of like a regular VR i.e. switch from dead ground high charge to resistive ground low charge depending on voltage n current sensed which would make a relay open or close???????? (verus the manual settings on a light switch)

HERES MY BEST GUESS of how they, work can you or Bob or Bob M settle this??????????

I guess they work kind of like a VR in that they sense the voltage n current of the genny versus the battery n switch from dead field ground for high charge but resistive ground for low charge buttttttttttt they arent as fancy n precise as a full fledged VR that uses kinda like pulse width modulation n relay chatter/switching to finer n better regulate the charge rate i.e. they have 2 stages ONLY Low or High charge unlike a VR that fine tunes the charge rate by relay chatter and pulse width type regulation

Talk to me, that how those Cutout Relays work that have the FLD terminal on them?????????????????????????????????????????????????????????????????????????
