WTF?? grn/red exciter voltage too high when plugged in??

More than a few times now I have read and heard conflicting stories about this. I am doing follow up tests on this new 3G. EVERYTHING is wired correctly, i have the 500 ohm resistor inline on the exciter wire from the gauges, the black/or wires are good, 4 gauge wire is there, way solid grounding. The volts on the yellow wire match the battery and the charging post. With the key on, unplugged the exciter voltage reads a little less than the other voltages...say 12.5v, where battery is 12.8 or so...Now, key back off, and plugged in the d shaped plug, im told, and read the dark grn/red exciter voltage is supposed to be down to somewhere arouund 3 volts!! I have tried repositioning the 12v switched source,, same result..This is a new regulator from a corral supplier, he was more than kind enough to help out. But, WTF,,, why am i reading this higher voltage??? ANYONE???

I truly do not understand why the voltage is supposed to drop to 3 volts, when the thing is still connected to a switched 12 volt source on the dash side, plugged in or not, the voltage source is still coming from that direction.

PLEASE HELP CLEAR THIS UP SO I CAN EITHER DISREGARD THE 3 VOLT THING, OR REPLACE THE WHOLE DAMN ALTERNATOR, WHICH IS BRAND NEW!!!
