This is where I'm at today, disconnected the jumper wire from the alternator output to the battery stud on the starter relay that I put on. Reconnected the original black wire to the output. With the key on I have 12.6 volts at the alternator and at the v reg, also have continuity from the other field wire connector to the v reg. When the truck is running, with the headlights and blower on, I have 12.5 volts at the battery. When I turn the lights and blower off, I get 12.9 at the battery. Any thoughts?
