That was one of the first things I tried. With the DMM measuring the voltage output of the Generator, I see a very rapid rise in voltage past 20 volts from the D+ and D- connections.

12 volts on to the field connection sees a rapid rise.
2 volts from the P terminal sees a similar rise but not as rapid but it still goes up dramatically and, not wishing to make things blow up in my face I discontinue the function. I also get a modest spark when I disconnect the jumper but it's not enough to mar my jumper, it's also a small 18 gauge jumper so it won't carry a lot of current (smallest in the link of the chain).
