Finally got the time to go mess with it today. Battery went bad on me a week or so ago, and just now got a new one. I tested the voltage with my voltmeter, and on the new battery it showed a strong 6V sitting. Before doing anything else, I unhooked a condenser which was hooked to the FIELD terminal on the generator (Because I learned it was a "no-no" from the previously posted links). Started it up and increased the RPM. First it stayed at 6, then gradually crept to 7, and crept some more to 8 volts and stayed there as long as I applied throttle. I thought maybe it was just recharging what I used up when starting the motor. Went for a drive, about 2 miles, under 30 mph. When I got home it was still showing 8 V with throttle applied, and 7 with no throttle.
If it overcharges, I may turn the regulator screw down a bit, but if not I guess I won't worry about it.
