'71 Duster 340 Battery getting overcharged

Got the two field square back from auto zone...they replaced the wrong one field alternator with no hassle. Put a VR on order as it was cheap and thought my decades old one could possibly be bad. Put the new alternator on and was happy to see 14.2-14.4 volts at idle. Ran the throttle up and was disappointed to see 17 volts. Shut it down and cleaned the VR bolts and star washers up real good and tried again...same thing. Wiggled wires and noted the green wire was getting hot. Shut it down and going to wait for the VR to come in tonight at 9pm...hope to pick it up in the morning around "honey-do" yard work. Hoping the new VR fixes my high voltage problem now that I have a two field alternator. I'll keep you updated.
