hrm...thats odd, I didn't think of the alternator as a switched device..when its spinning it makes power, when it isn't it doesn't. Its not like an accessory..meh, I'd agree with Will in that A) It shouldn't happen and B) Its a sign of things to come..I'll throw in a C) I'd replace it before some circuit fries and it sends mega-volts up the wire and takes a few other parts with it.
After seeing the nightmare up in Seattle a little while back you maaaay just wanna see if there'* continuity between the alternator housing and the + on the battery. Just had that image flash in my head...eek

So it makes a loud buzzing when the key is in the ON position, just before you turn the key to start? Does it buzz when the car is running? if not then mine does it too, my dads camper van (305 GM) is LOUD when the starter is engaged. My 90 does the same thing but its not very loud. As long as it doesn't negatively affect anything you should be OK.
EDIT: um im thinking of the starter.... (*whispers*... this is ackward....*whispers*)
