Wait a tick. I just had one more thought.
When I turn on the key to run the 3 indicator lights (parking brake,
brake wear and low fuel) all come on dim.
I seem to vaugely remember that field current comes through the
instrument cluster. What if the alternator indicator bulb failed?
Then the alternator would not generate, unless the residual magnetism was
sufficient to bring up the alternator (somewhat unlikely, I guess).
It still sounds like a bad ground. Parking brake, brake wear, and low
fuel indicators are independent of the alternator and are directly
powered by 12 volts.

I think it is worth a try. The Charging light should come on when
the switch is turned to on and the engine is not running. I know for
sure that my BMW airhead will not charge if the light burns out, and
I know 110/111 MBs were the same. A bulb is a lot cheaper than a
new alt.
Since the charging light is not lighting, I would guess you have no
charging. Some feedback might cause the other lights to light.
