Robert, I dont work on those alternators, but my best guess if if shes cranking out 16 volts even coupled up to a battery for a load (is it??)

ANDDDDDDDDD if theres a good wire from its rear main output stud to the lil side No. 2 Voltage Sensor Terminal (or else to the battery) IS THERE??? cuz thats where it senses voltage to perform its internal regulator functions.

Then I suspect YES its an internal regulator problem, but Im not sure nor I bet your local auto parts house does either if you can buy it seperately. If theres an alternator repair shop nearby, Im sure they can tell you.

On your new Alternator wiring, as far as that other lil No. 1 side Excitation Circuit terminal, I ALWAYS recommend a 10 ohm current limiting safety resistor which could serve to protect the internal diodes, and then if she still tends to run on even after the ignition is turned off, I then add the diode to prevent backfeed.

Let us know how it turns out
