I've run into some electrical trouble. Still trying to figure out if it's the stator, regulator, or battery. I'm undecided still. The battery was reading just 11 volts. But there are some other flags I'm chasing down still.
Oh, and riding in a significant downpour caused a short somewhere. It goes away when the scooter drys out. Might have been the trigger for my electrical problem.
Stator open circuit resistance: 3 ohms.
Stator open circuit voltage: 30 - 70 VACrms. Sure is fun to use an oscilloscope and see the waveform!
