Maybe you have a bad battery and the alternator can't get it to go above the 13.6.

The battery was reading 12.5 volts when the car was not running. I apologize for failing to post that info. The choice I am faced with is either "some of the windings are going bad and it can't keep up under high load", or "maybe the regulator". I would definitely prefer the latter. I do have a spare alternator, but that is a card that I would rather not play, unless unless I absolutely have to. I can try swapping the regulator from my spare one into the car to see if that is it or not.
