The alternator makes alternating electricity. It uses diodes to convert it to direct current. That being the reason it is called an "Alternator". The alternator uses constant reference voltage and then diodes to convert alternating electricity to old fashioned direct current. I have seen an alt disconnected with the engine running and generate about 400 amps at 27 volts.
That simplistic generator does just that. It generates. It does not need a reference voltage to "generate".
So if the battery gets pulled on an alt, the alternator will full field and can possibly blow out the electrical system. Been there, done that. Same trick on a generator and they can keep running. Time for me to take my wrong self to bed. 147 day's to retirement from work and then maybe I can work on something else. Perhaps more so, "Volunteer".
