No need for the carb#
I was only asking because that's the only other thing I see in the key on white/black wire circuit.
This should also excite the alternator according to the schematic I'm looking at.

You were doing the right thing helping another living thing(s).
The truck can, and will, get fixed.
(edit)
I see, the colors are different in the one I'm looking at.
I still don't understand why you "have power at alternator ground".
Now that we're on the same page, what are you confused about?
