So, I've had some success with this, but not going to write it off until I'm satisfied it remains good. I guess I'm paranoid after all these little glitches.
I pulled the stator and bench tested it; it checked out fine. I tried bench testing the 3 R/Rs I have and had mixed results. Two of them had sketchy readings and the newest one had decent readings. I showed nothing, anywhere in the Ohm setting, but on the Diode setting is where I had results.
I did some checking on the bikes harness and reassembled everything. I did find a pin in the Stator connector that was back out; when I pushed it in it clicked.
With a freshly charged battery (13.3 VDC), I was reading up to 13.5 VDC at the battery revving the engine. I took a ride and saw 14-15VDC, but that was without the headlights attached; once re-installed, I was reading 13.0 VDC.
I had some confusion with the R/R pinout, but can't seem to find any reliable info on it. My wire arrangement didn't match that of the Tank 150 manual I was using.
Slightly difficult to read the 13 volts @ 4K RPM.
