My Gen II alternator started experiencing intermittent overvoltage so I finally started looking at the charging system.
The Gen I alternator has no positive lead attached so it does not appear to be part of the charging circuit at the moment.
Both batteries are charging at the exact same voltage so the they must be wired in parallel with the Gen II alternator.
The Gen II alternator has only the exciter leads and the positive lead attached. This must mean it is case grounded and therefore not an isolated ground alternator.
Is there a way to test an alternator for an isolated ground without tearing it apart?
It seems for an easy fix I could buy a case grounded alternator like the one from an 84 eldorado or buy an isolated ground alternator and attach a ground wire to the frame.
Am I correct in my thinking? Anything I should look out for?
