Is there any way to control the PM alternator?  In other words, can you turn
it off?

        These are really minor details. The electronics is pretty simple, at least for us electronics types. The hard part will be the altrenator itself.

        I would think that if designed correctly, you would not notice much difference from the "normal" alternator set-up. The main alternator would charge like it always has. The "low voltage" light will light up when there is a problem.

        The only differences would be:

1) You will test each alternator separately during the run-up, a lot like you would do with magnetos.

2) There would be some sort of warning if the back-up alternator started picking up some of the load while in normal flight.
