Re: Alternator getting hot

GM switched to using alternators on the sixes and v8s in 63. They kept the generator words on the instrument cluster for some reason though.

Re-charging the battery could cause some excess heat. What definitely will cause it to get hot is if you have too much resistance somewhere in the wiring. I had some heavy resistance when turning on the a/c that was wired through the fuse block. Switched the wiring to run relays to power the a/c and my excess resistance went away. No more charging issues for me.
