A question.
Is a fully charged 12V lead-acid battery held at 14V a voltage stabiliser?
People seem to think so but I doubt it.
If you disconnect the battery while the alternator consistently puts out
over 13V will there be much difference in AC components on the bus?
Is there an AC on top of DC internal impedance measurement out there
somewhere that I can't find a reference to?
I hope somebody knows more.
Thank you.

The battery in the circuit will help dissipate voltage spikes. If your
generator goes into an overvoltage charge situation it won't take long to
boil the battery. Once that happens the buss will go overvoltage too,
