Voltage regulator sends a current to the alternator to tell alternator how much voltage to output.

Check the alternator and voltage regulator grounds.

Had a bit of time this morning, so first thing I did was test battery voltage 12.56V. Then pulled the green field wire off the alternator and started it. Tested voltage across battery terminals 11.85V, so no ground short in the alternator. Plugged green field wire back in and got almost 19V, then pulled Voltage Regulator wire, and Volts dropped back to 11.85V.

Cleaned the VR grounds but they all looked good and tight, so I went ahead and replaced the Voltage Regulator with the original. Started the car and now have 15.1V with fast idle. Still a bit high, but I will get a new VR and see how it goes.

Found this upon further inspection of relatively new Voltage Regulator:
