The old generator appears to be a 3 brush generator also, but it has 3 wires running to it like a 2 brush generator it has a field and a ground wire running to it, but the new 3 brush generator doesn’t have connections for them🤷🏻♂️
I’m also trying to install a 3 brush generator on my 1948 8N that was originally equipped with a 2 brush generator, I can’t figure out how or where to hook up the generator ground wire on the generator, does it just get screwed to the generators case?
