    i've always believed it was the field windings that need to be polarized in the gen. ...

    Welp...the third VR tested out bad at the rebuilder's shop. He's actually questioning the integrity of his testing equipment and told me to slap it on the car to see if it was working in case there was something wrong with his test bench. Nope. It's dead alright. Gonna order up the Lucas (shudder) electronic VR and see how that goes. I will say that the return process with RockAuto on this current bad VR was seamless and easy. They even sent a pre-paid return label.

    You do not polarize regulators, you polarize generators. You only need to do this if the pole shoes in the generator have lost their magnatism. You send current through the field coils in the normal operating direction which will add enough magnetism to get the generator charging.

    Yes, I understand this, but the person asking the question may not have. My point was do not attempt polarization with this regulator or you will destroy it because of the type that it is.
