Yeah, flames shooting out from under the hood, that kind of thing...
On my '93, the positive terminal is so close to one of the A/C lines that I can't get jumper cables on it without a lot of contortion and a little praying. However, if the battery was grounded either through direct contact or via shorting of one of its heavy cables, the result would be near-instant car death, not a trickle-down lasting all night.
I don't see the original poster reappearing yet, but my bet was that it was due to a wonky alternator either undercharging or overcharging his battery, depending on which component was swapped most recently (I understand he went through something like six). My Bonne is on alternator #4 right now, a genuine Delco rebuild, which has lasted several years now but which is starting to get a little... um... suspicious again.
