[Knut's personal opinion: I don't think a properly functioning electrical system requires such exotic alternator work-arounds. I suggest spending energy finding and fixing the root cause.] [MODERATOR's NOTE: Although it's fun to imagine the things that could be done along these lines, because this all appears to be speculation I have killed the thread. Feel free to send additional notes directly to Walt.] Walt, If you really undertake this project, then consider a clutch from a dead A/C compressor. You could electronically select the belt that way. Better still, put in a SECOND alternator geared for low speed that would cut off above a certain speed. That way you'll have a pair of alternators and belts, which is a Highly Available configuration. Personally I don't think it's that much of a problem. It's been 112 degrees here (!!!?!) and city traffic has caused my D no difficulties: voltage, overheating, or otherwise.
