Could you jump from the batt positive to the VR blue AT the VR AND from the battery positive over to the male terminal ON THE ALT that has the blue wire on it(keep it plugged in) AND jump from the other male field terminal ON THE ALT that has the green field wire on it(keep it plugged in too),jump it over to the VR green terminal(again at the VR) AND jump from the battery positive over to the alt big battery terminal. This will feed full battery voltage to the alt field, the VR & connect the batt & alt directly & with your good/clean jumper wires/alligator clips will eliminate the bad connection issues and I almost forgot(one more) run a jumper from the VR case to the batt negative post.Were going to get it all this time! Run it at a fast idle & see what ya got.
