Diagnosing high voltage

Ok, starting over.

...Disconnect the green from alternator, make sure it does NOT charge. If that is true, take a alligator lead and ground the field that was connected to the green. Make sure it charges and it will OVER charge. Reconnect green

Voltmeter is pegged, 17V.

2....Disconnect VR connector. Run and make sure it does NOT charge. If not, make sure VR is grounded. REALLY grounded
RE check voltage as close to VR as you can get. IT MIGHT BE time to find a pin/ needle to puncture into the VR blue wire terminal at the VR with it all connected up. RE-measure V drop between VR blue terminal and battery plus. If this is OK,

Again, voltmeter pegged at 17V with VR disconnected.

Voltage drop at VR with key in run is 0.20V.

VR is grounded and connector looks good.
