I just put a '95 alternator on my '93. the truck previously had an internally regulated GM alternator on it that didnt work worth a crap. i installed a factory '93 harness when i installed the '95 alternator, so its all wired correctly.
my question is this: how can i be sure its working properly? my voltage gauge shows high-11 to low-12 volts almost all the time while running (i let the truck run for over an hour). unlike most '93 w350's, mine has an electric lift pump in the tank, so i know its pulling at least a little bit of power when running without lights.
any ideas or advice? i dont want to get stranded anywhere. is there any other electrical component that could be causing such a low voltage? i would assume that i should be seeing between 13 and 14 volts, but i guess i could be wrong.
