I didn’t have time Today to test the HEI except to note that it has several wires attached. I’ll check them all tomorrow.
I did note while in the cab that when a load is put on, say headlights and heater blower, the ammeter does not respond. Not sure if it should or not. I checked the two shunt fuses, they’re fine.

There should only be one wire feeding the "BAT" terminal on the HEI and it should show 12 volts on the multi-meter when the ignition switch is in the "ON" position.
Don't even worry about the ammeter at this time.
