By static voltage I assume you mean bike not running. The voltage reading indicates state of charge. A load test is needed to confirm your battery condition. 12.8 is 100% for a conventional battery, a little under for an AGM, though more than good enough to start the bike. Some trickle chargers will not fully charge an AGM battery, depending on float voltage.
By dynamic I assume you mean bike running. Low reading. Any increase with engine speed? What is your idle speed?
Try a few more RPM on the stator test. Your (not very) low reading could be a result of the tach reading a little high and meter tolerance. Anyway, 42 on each leg should not be a problem.
Forgot what you ride. Single phase or three phase system? Any signs of high resistance where the regulator connects to the stator?
Anyway, sounds like your regulator is toast (assuming you checked the 30 or 40 amp fuse and regulator ground).
You are correct in your assumptions as to static and dynamic voltage.
There was no increase in dynamic charge with a change in rpm - idle is set slightly over 1100rpm
In the Stator test I got 70vAC at 5000rpm - is that ok?
I tested the regulator/rectifier again and had continuity between the GREEN output wires and the YELLOW input wires in both directions. I believe this is where my problem is. I don't have continuity between the RED output wires and YELLOW input wires which would mean that the diodes within the rectifier/regulator are toast? There is no signs of burning or overcharged wires.
