I would first check to see if the alternator is actually grounded. Mine was not and the voltage fluctuated due to a floating ground. I physically checked via a Voltmeter (under the car) the voltage from the alternator output to chassis ground and then ran a 10 gauge wire from the alternator body to chassis ground and again checked the voltage. Lo and behold, the voltage went up to 14 VDC and has been rock solid ever since.

Some alternators (Pep Boys) do not have a ground point to connect to. I assumed that the alternator would be grounded through the nut/bolt setup. But this time it was not. So, I ran a wire from a point on the alternator body to chassis ground.
