This would be the same as a pulley clutch on a typical automotive AC compressor. Shouldn't be hard to adapt one... or should it...?
In any event, does anyone have data on how much load is created when the alternator is spinning but with out electrical load?
And perhaps the easiest solution is putting a switch on the field windings.
