Okay, heres the story......Alternator goes out so I replace it with one from Pep Boys ( I know, bad decision). Anyway, new alternator is only putting out 11.7 volts on my meter while its hooked up to the battery. I take it back and the guy says its putting out 15V on his machine. I demand a new one anyway and they replace it. This one is doing the same thing.
Could there be some sort of short causing it not to charge?
Could the alternator not have enough amperage to charge the battery?
Any help would be great, thanks.
