It's a 1967 C10 with a 250ci engine. The truck has an alternator, it's plain no power anything just a radio. Someone local said they thought it should have a 35 amp alternator but were not 100% sure. Does this sound right and if it is should I try a 30 amp or use a 50amp? Mechanical work I'm ok at but electrical systems not so much.
Thanks,
Mark
