I posted this question a few days back, got no replies and have since figured a few more things out, but I need HELP out here, people, PLEASE! I have a 65 that we dropped a crate motor into and switched to GM's serpentine belt system. It originally had an alternator with an external regulator. This car has the old ammeter gauge in it, too. The new alternator has 3 wires on the connector. Following the advice from this tech section, I connected the fat lead (first from left) to the "BAT" terminal along with the red wire coming from the battery. I connected the middle wire on the connector to the blue wire that is connected to the brown wire at the location of the old regulator. The other wires were taped off. The alternator didn't charge. The ammeter reads on the discharge side of the gauge when any accessory is used. The mechanic who is helping me out on this project said the new alternator is the same as a 90's Camaro type and the field needs to be energized with a ignition switched 12v source. I connected that to the "F" wire (last wire on the connector)and still no charging. I disconnected the blue wire and grounded the middle wire and still no charge. I switched two wires around and still no charge. What is going on here?
