Want to make sure I don’t burn anything down here: I’m getting a 100 amp alternator (Powermaster, self-exciting) to replace my ac delco 63 amp. Currently, the bat wire goes from the back of the alternator to the starter (8-10 gauge I think… maaaaaybe 12?). I also have a fusible link at the...
78 c20 I put a new alternator and battery in and on a cold start I get about 15 volts charging, but when I turn it off and start it again I'm down to 12. If I turn anything on electrical at this point it just drains the battery. Any ideas what's happening, she was fine one day then all this started.
