Baffling Charging System Question

First thing to check is if your voltage regulator (Im assuming electronic) is grounded properly, loosen the bolts on the regulator and then tighten them a few times. Next (with the ign on) you should have 12v at one of the field wires and some resistance on the other, the electronic regulator controls the ground resistance in the field as opposed to the mech regulator which controls voltage to the field circuit.
