My alternator was getting weak, but before i could change it, i went to go to work, and after starting and turning on head lights i saw alternator gage fall. put it back in garage and changed alternator and battery and now refuses to charge. checked all connections and seems to fine. HAD NEW ALTERNATOR TESTED BEFOR INSTALL, DUE TO THE FUN JOB OF WORKING ON A VAN. could it be something from the small wire clip and where do these wires run to and what for. THANKS FOR ANYONES HELP, Sinserly Rich

I'm not sure if its a 4L60E, or a 4L80E.
