Well put in the new regulator and no success..... Frustrated.. So with the new regulator ,cut out relay won't connect when truck is started just like before.?. Gen light still on before I manually close the relay I only get a 2-3 volt reading at the regulator post both arm and field. Close it and volts raise to match the batt at around 12.5 or so ,while it's closed and light goes off. Volts rise at batt, arm and field posts when rpms raise only when cutout is closed..? It was getting dark as I was doing this and I noticed sparks in the generator as I advanced the throttle so I turned it off..? Now I am thinking going to an alternator. But only cause I need the vehicle and it almost seems easier at this point , having spent so much time figuring out the gen/ reg stuff only to have not isolated the issue. Feeling a lil lost. Maybe it was my generator this whole time.??
