Alternator Troubles! 1973 Plymouth duster 318
Here's how I wired mine up. The relay is in there to eliminate the flickering headlight syndrome. This is typically caused by dirty ignition switch contacts. If you don't want to use the relay then just connect the blue wire that is coming from the ballast resistor directly to the I (ignition) terminal on the regulator and then over to one of the field brushes on the alternator. The green wire goes from the regulator to the other field on the alternator. Hopefully this helps you.
