The truck I am puzzled with is a 85 .This truck was a 22ER EFI. I DROPED A BUILT 4.3 IN AFTER THE 4 CYL DIED . I am using a GM alt but my truck woud kill the battery overnight unless I unplug the alt. I had the same problem wity the 22RE alt before the motor swop . I was wondering if anyone knew of a relay or something that might be in line on the wiring before the alt . The alt I am using is for a 93 s10 . I glad uall give me some input to the alt collors to connect mine were right but i was starting to wonder.
