Do not get a "remanufactured" alternator from a parts store; they're junk. You can get a brand-new Chrysler 46-amp alternator from Wallwork. Get a good new voltage regulator, Standard VR-128 or NAPA Echlin VR-1001. Run a ground wire, 14-gauge, from the "GRD" hole on the back of the alternator to the voltage regulator base and from there to the battery negative terminal.
