Also Craig, do you have any VRs that you've pulled off that "might be good?" If you are good at soldering, you could directly solder some wire leads (no 18 or 16) direct to the VR terminals, and use that for a "guinea pig." You can wire it direct to battery, direct to alternator, and make a no10 jumper wire from the VR mounting hole to the battery NEG
If you cannot solder and want to spend the money on shipping, send me one, I'll test it, solder some leads to it, and send it back
