It is very possible that your alternator is self exciting, as is mine (only one thin wire, disconnecting which doesn't do anything). AXMonster started a great thread (
Automatic alternator cut out/regen braking), where got down and dirty with his internal field alternator, but it appears that rewiring the diodes inside wasn't enough
It's worth a read, though, and your alt might have a slightly better (= easier to hack) design.
