Ah, that explains some other issue I have. In my flying homebuilt,
(the one I had to buy that was finished and flying because I didn't
know it would take so many years to complete my Glasair) It's amp
meter only shows a charge, but will never indicate a discharge. It
just goes to the center position when there's a load and the
alternator isn't turning. So where I the best place to install a
shunt? I need to rewire that darn thing.

Sounds like the ammeter is installed in the alternator's
output line. Doesn't belong there. A shunt won't fix that. The ammeter
should be connected like the diagram in that website I pointed out
ealrier: between the master contactor and the bus. Do that and all
will be fine. Piper used a loadmeter for some years, which was an
ammeter that had its zero position on the left instead of center, and
was used to indicate the alternator's output. Maybe that's what the
builder of your airplane was thinking of when he connected it between
the alternator and bus.
