Rusty, a PM alternator won't experience the overvoltage problems of a
standard one. 

 
Thanks, but that wasn't really the question.  I would have two alternators, and would want to be able to test them individually during preflight.  Also, I'm using the EM-2 as a voltage warning, so if either alt was working, I'd have no alarm. 
 
I'm still not all that crazy about having dual alternators.  I'd like to see the e-shaft alt putting out enough for primary duty, and perhaps it can, particularly if they can "stack" them.

With an alternator driven by the e-shaft and an EWP, I could have an engine that required no belts.  I REALLY like that idea.   Did I say I REALLY like that idea?  Paul Conner
