All good thoughts guys.

1st, yes we have tried 2 other digital meters and one analogue.

2nd, have tried tying the smaller red wire directly to the large terminal, no luck.

while running with the white wire disconnected the alternator shows no charge as expected, touch the white to any of the positive connections and it kicks off just fine but stays high no matter if the white wire is connected to something or not.

We have also run the smaller (white) sensing wire directly to the bat output side, no luck.

Jack, I would like to know more about the 1st exciter terminal. I am guessing that you are referring to the smaller red wire here and not the white?

3rd, I have a voltage reducer for the gauges and they appear to function normally.

1940, good hint on the battery gauge function. I will check the link you posted, thank you.
