Re: help after swap wont charge
sounds like the alt isnt gettin a reference voltage. There should be a constant hot and a switched source hot on your alt if its a tpi style alt. take a picture of where the plug goes into the alt and ill can tell ya witch one needs what.........i had the same problem on my old setup it was an easy fix
