    have you had these alts tested that they are working correctly?

    there is a black plug that goes into the alt, one of the pins has to be wired hot when ign is on, or it will not charge the truck.

    shit just get a alt with a lifetime warrantty. you might get stuck some where till you figure out the problem but at least you wont have to keep buying alts.

    Find out from the wiring company if you have the harness for the one wire alt.

    Also what alt are you using, ie. When you bought it what vehicle does it belong to?


    A picture can speak a thousand words, but not in this case. Need more info
