What you might try if in the mood...
to round out your test with the bulb in-line...
Remove the bulb again and start the car. Test to be sure NO charge from alt. Then rev the engine to 2500-3000 RPM and see if the alt then self-excites...
Sounds like a resistor to give the proper voltage down grade going from the output post of the alt to the excitor wire might be an easy back-up link and still keep the dummy light connected?
