I use the GEO alt and an advantage with it is that if you
kill power to the exciter lead it will stop the power output so you can shut
it down in the event of a voltage overrun.

East Coast confirmed
that the UltraMini works like that as well. After seeing Mark's message, I
called around, but the cheapest I could get one was $135 + $35 core, and that
was for a rebuilt unit. I just went ahead and ordered a new alt
from East Coast for $219.
Now, the problem will be
coming up with a double pulley. They said the shaft was 15mm, and the
normal size was 17mm, so finding a double pulley might be tricky. If
I can't make one work, then I'll have to consider using just a single V
belt, or trying to convert to a serpentine belt. On one hand, a
dual belt seems like it would be twice as likely to keep the water pump
running, but in reality, it's not. If the outer belt comes off, the inner
could remain, but if the inner comes off, the outer belt will go with it.
It's tough to say if it really offers any redundancy, but it does offer more
contact area on the water pump pulley, which has a
terrible geometry already.
Cheers,
Rusty
