Thanks for the reply, Mark.

The diodes are not anywhere near the batteries ... that I have found. The diodes are somewhere downstream of / between the Alternator Restart Switch and the respective alternator.

I think both my diodes might have failed closed as I have .6v at the rear alternator field terminal, and .3 volts at the front alternator field terminal. So, I need to find them and replace them.
