So a calculated resistance coupled connection between two alternators
would allow the alternators to run separated systems and allow say a
second alternator to back up the other system while not loading it
down. Food for thought.


Current equalizing resistors is another way to do it. It's common
practice in SS audio amps to use emitter resistors to equalize the
currents between parallel transistors. But I would hesitate using them
with modern alternators because I don't know how it would screw with
the regulators -- some have a local sense line and others have a
remote sense line -- a resistor in the load might send the regulator
into seizures.
