Here is what I got when I did this last Feb:
"From orange wire terminal on back of alternator to ground for voltage regulator - 12.5 volts (battery geting a little low). No change when I reved it up. The regulator was plugged in.
Unplugging the regulator and jumping the two terminals the voltage from alternator to regulator ground was 14.5 volts and as I reved it, it was climbing to 17 to 18 volts."
Next warm day I guess I will start testing all over again. I may put the solid state VR back in.
