That actually sounds like there was corrosion between the alt and mounting, where moving it made the voltage jump up. Bad ground from the body to the motor will have this effect too.

I checked the grounding between the motor and body...the braided strap around the motor mount is in perfect shape and solid. I grabbed it, yanked on it and its good. I did resistance checks from motor to chassis alternator case to motor and then to chassis and twice I've had that alternator off and on, including tightening that belt.

Sounds like time for a new belt or something is loose in the alt, or the 2 prong plug needs replacing.

AMC/Jeep gauges are for amusement only. Any correlation between them and reality is purely coincidental!
