Diagnosing high voltage
Not sure why you are still trying to diagnose the problem.
You stated that there is low numerical resistance to ground on both field wires with both field terminals removed at the same time.
That says that one of the terminals OR an I thermal shirt exists
The fact that you can remove the VR connector and it is still charging Proves that as well.
PULL THE ALTERNATOR, TAKE IT TO THE PARTS STORE, HAVE THEM TEST IT, THEN GO HOME WITH A NEW ONE AND INSTALL IT.
AAAAARRRRRRGGGGGG!
