IT'S BAAAAAAAAAAACK.
*insert a billion curse words*
I have ONE option left: rewire-the terminal in hopes that it's a bad connection. If that doesn't work then It's back to the Alternator shop for an inspection.
I tightened everything tonight and the lights stayed on. Oddly enough the battery charged to 12V even while all the lights were on.

I'm irritated and worried. Good thing it's almost friday.
I'll be following RETed's advice about the checking the charging system with a DMM and see if I can further pinpoint the flaw.
DAMNIT!
