Well, here's the verdict..... battery!
The belts are fine, the alternator is charging at 13.4V on idle, the battery is just not holding the charge. Last night I drove her around for an hour and tested the battery... 12V. This morning I tested again... 9.4V.

Buying a battery today.... should be a lot cheaper with Larry's $5.00.. Ha, Ha...
