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.


Frank it is very easy a single regulator will control the field voltage
on
both alternators. This way they would run the same and share the "Load"


I thought about that, but wouldn't the rotors need to be locked in
phase?


Phase? The control voltage is DC, the outputs are DC, am I missing
something? I know that the output of an alternator isn't "pure' DC,
but it will never be 180 degrees out.

Alternators deliver 3 phase, approximately 120 volts output at working RPM.

Yes I know that, The output (at least on most automotive applications is
DC.)
I have seen modifed alternators with 3 transformers on them to provide
higher voltages for B+ for transmitters.

BTW Randy, I wasn't trying to be a smart ass with my answer.

I didn't take it that way. NP!
