You have a short in your electrical systum, the short is drawing so mutch power that it is draining the power that your alt. creates. you need to find the short, first check all the lights for a bad element in the bulb or a faulty ground. then pull fuses to eleminate different curcuits.
the alternator came from autozone I think the regulator is wrong . from what I read it is supposed to be self enerergizing . once you rev the motor it charges fine . belt ok and pulley is right . thats what I get for trying to save a buck .
