Thanks Jerry - I added that wire originally when I re-wired the truck and it is still there now (and the regulator case measures at 0.2 Ohm to the generator and any other good ground). So that is not the issue. I wouldn't bother the forum until I exhausted all avenues I could think of.. now I do not know what to do. I thought maybe the ammeter was faulty, but the voltage stays at 12.5 or so when the engine is running from about idle to 2000 rpms. Is there any condition with the generator spins during the motor test, but is still faulty?
