Charging issues
Here are some pics of the alternator I got on rock auto it was the best one that was a direct fit not sure of the brand on the VRThis is most certainly NOT charging, OR the output from the alternator is NOT actulally "making it" to the battery. Check the output stud of the alternator when running and see if it s "same as battery" or way high. If "same as battery" AKA 12. something it is NOT charging
OK how do you have the alternator wired to the vr and what model IS the VR, that is 69/ earlier Mopar, 70 / later Mopar or some other? What exactly is the Delco, model, or series, what is it off of?
IF you are using Mopar regulators, there are two major differences......the 69/ earlier (came with your car) has one insulated field terminal, and the other end is grounded through the brush holder. The VR is grounded, and gets 12V power from the "run" circuit, and the VR controls the amount of field current to control the charge.
On a 70/ later system, the field has BOTH ends insulated, and one end gets 12V and the other end goes to the VR, which controls "the amount of grounding" of the field, which in that way also controls field current and the amount of charge.
I cannot tell you how to test yours until I know what you have.........maybe post some photos of the VR/ alternator and wiring
