Charging at 15.1 volts. Anybody?

Stopped at NAPA on the way home and picked up a new Voltage Reg. I bought their best one to replace the Autozone VR. After installation of the new VR, I started the car and checked the voltage and still 15.0 to 15.1:angry7:. Oh well, now I know I have a great Voltage regulator. I got out another volt meter just to make sure this one was right and they both read the same. I even ran a ground jumper from the VR to neg on battery and still the same. I know I'll figure it out It will just take a little time. Keep your thoughts coming please.:-D
