i think it adds a rester too the fieldand the to drop the amps in the
arm. wire to keep from shocking the gen.
thats how the 3 term civy ones works
and the cutout opens wane the gen arm. volts is less than the batt volts
i think
a 30 year old moters car repair book will say this stuff better than i do
you mite need a 40 year old one
