I will tell you that one truly set up to be "one-wire" will need to hit self-exciting
rpm to actually start producing voltage. It depends upon the model as far as rpm but
800 wouldn't be unusual.
Bring it up to somewhere near there in rpm and get out your volt meter.....

The one wire on my 8ba charges as soon as it starts. I think it depends on the alternator but not sure. Grounded the alternator and ran one wire to the positive side of the 12 volt battery.
