Over charging
Somehow determined the field wires are 'good' What was the test or check ? Used an ohm meter on the wire to check
Continuity with an ohm meter means just that, and only that.
In other words, there is continuity between two points. If it shows measureable resistance, then there is continuity but its not good enough to do the job it needs to do.
If it shows no more resistance than touching the two probes together, then its probablyt OK but might or might not be good.
What I'm saying is if there is one strand of copper connected, there is still continuity, but there will be resistance to current flowing through.
Then connected a test light from the battery positive to each field terminal on the alternator. not sure what i was trying to prove with this(checking grounds) but found it interesting that both male connectors on the alternator fields signaled as ground. maybe means nothing.
If both field wires were removed from the alternator, then the field circuit has a short to ground.

This
may explain the uncontrolled alternator output.
If the brush connected to the run circuit is properly insulated, but the brush to the regulator control is grounded, then the rotor will be fully powered, full time.
In contrast if the wire from the run circuit was connected to ground, then the rotor would get no power but battery would dump maximum current to the ground short until something melted. The ammeter would show major discharge until the connection was broken.
