Ok, 12 month ago I converted by 54 3100 to 12V having my gen. rewired and changing the reg. to a 12V reg.
This passed weekend decide to convert to an alternator. Bought the alternator harness and wired it up. Seems pretty easy. Start the truck, checked the voltage at the battery while run, 14.25V, seems ok. Turned off the ign. key, but engine stays running. What did I do wrong?
