Is your 12v key on and starter wire tied together?
@Blake Andermann Thanks for responding. W13 and w19 seem fine. Problem seems to be with w51. Starter keeps running until I disconnect w51 then the starter stops spinning. Should I not be using the original 74 starter relay? Or should w51 go to the small post on the relay?
