Sorry to bump this up from the relative stoneage, but it appears no one ever addressed this.

I even tried running the headlights, rear defroster, fan, radio, etc.... No voltage dip. I'll just have to run it killed for a few days and see what happens.

There is nothing wrong with your alternator kill switch. Car batteries are 12.8 volts when fully charged, not 12.0 volts.
But, as you've discovered, the majority of the loss in the charging system is from the belt drive.
