Maybe I'm missing something here or else my knowledge of car electrics has
not been kept up to date.
The only time I disconnected my battery and ran the engine without it I
blew my headlight globes since the voltage rose above 12 volts. Is the
output of the alternator regulated at 12 volts or a little more in a
modern car.
Patrick's 2000 rpm would have my car travelling at more than 70 mph. Not
recommended in this country!
