It could be the regulator/rectifier or the stator. I would get a wiring diagram and go over the wiring good to make sure nothing is wrong with the wiring, first.

I don't know if I understand your question, but if you're asking how it's supposed to be wired, it should have 5 wires, three yellow wires, a green wire and a red wire. Three yellow wires run straight from the stator to the regulator. The green wire is just a ground and ties into the green ground wire running to the lights and to the ground on the ignition coil. The red wire is spliced into the main hot wire running from the post on the starter solenoid to the keyswitch.
