Alternator output was 12.7 volts when the levels were dropping, and raised to 13.8 volts when it seemed to kick back on and started to recharge the battery. I think what is happening is the alternator is letting the battery drop to too low of a level before kicking on and recharging. I'm beginning to think the alternator needs replacing. The car is nearing 90K and I believe it is the original alternator.
