Hi Ed, if you discharge a battery below 10V they are sometime permanently damaged. You may have a shorted cell that makes the alternator work harder?

Could be a bad breaker, Rusty.  But since those are fairly simple devices, I wouldn't expect it to reset if busted.  I will report what I find as always - busted alternator OR busted circuit breaker {:>)

Simpler than a fuse :-)  

I'm curious, what amperage is the breaker?  Have you ever measured the current through it during operation?  I recall that I used a 5A breaker on the RV-8 (35A alt), which was the only breaker in the entire plane.  The only reason I had it was to allow electric Bob's crowbar circuit to work.
