You have the MZB right?

Don't know if this will help but I'll post it anyway, from the Yamaha service manual. I think you may be on to something with the voltages on the green wires, I know youre not using the factory regulator but using the factory diagram it seems that green wire at regulator should have around 1.5 volts and nearly nothing at black wire. And oh yeah, awesome build!

That's a great schematic. I haven't seen that one with the resistance specs.

I went back to my shop today and messed around for a bit. Now I have battery voltage flowing through the regulator from D+ to the Green Field wire, giving me battery voltage at the ring/brush connectors, through the rotor, and back through the black wire.

There doesn't appear to be continuity between the black wire terminal on the 10si regulator to the steel base, which I assume the base needs to be grounded.

I'm also unable to start the bike to test because I have the tank of preparing it to repaint. I didn't have any clear on the tank, so any gas that dripped on the paint ended up ruining the paint job.
