Wow, I'm glad I mentioned that part offhandedly! Also, thanks for
letting us know what it turned out to be.

Probably, but considering that every "dead" old alternator out there has
one on it that is probably good, it ought to be easy to scrounge one up.
I just looked in my box of spare alternator junk, and although I've
saved 7 voltage regs that need brushes, I only kept one spare
So, go to any junkyard that has foreign cars (Bosch alternators all over
the place), or friend with a field full of dead rabbits, or try calling
someone like Chris at Force Five to see if he'll sell you one.
Then again, maybe a new one is cheap at the dealer?
