My charging light is fixed. The smaller "F" terminal wire connector had
slipped off the generator. Completely unrelated to bypassing the dash light
rheostat. A quick tightening crimp of the female spade and I was back in
business.
I discovered it on step 3 of Randall's troubleshooting directions.
Surprising that the car would run without it being connected and was even
still charging 8-9 volts. (step 2). Ah, the mysteries of electricity.
Thanks for the help, everyone.
