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 output is DC, am I missing something?
Wouldn't you just want the outputs to be at the same level?

The control (field) current is fluctuating DC, isn't it? Isn't that
how the regulator smooths the output (which would be fluctuating DC if
the field current was steady)?

That's the plan. But regulators are like little kids with a new toy.
When you put two or more regulators in parallel (without current
equalizing resistors) it's almost impossible to make them share the
load equally.
