I got a chance to try Patrick's diagnostic, and I got something, but not what I hoped for.
Removed the ignition light from the dash for access. Pulled the double green wire off the ground spade of the light socket. Ran a fused jumper between the accessory terminal on the ignition to the grounded lug of the ignition light.
Turned key to ON position. No light.
Started engine and light came on while cranking and extinguished when engine started.
Ammeter was slightly negative (~1A) with engine running. Turned on headlights and ammeter dropped to ~-12A. Revved engine, but ammeter didn't budge.
I'm sure I learned something, just not sure what. Maybe that I can definitely eliminate the gauges as a short path?
