Thanks for all the replies.
I pulled the alternator and had it tested at the shop. The rectifiers and
diodes are fried. He is fixing for free, but it is a big pain since the unit
was rebuilt about a year ago.
The guy at the shop says that I have a problem with the charging system and
guessed that it was the (external) regulator. I've ordered a new regulator
from Moss (tried TRF, but out of stock). Hope this fixes the problem as the
show is on Saturday.
