Battery & Warning lights on

2009 FLSTF Fatboy

So first pulled some codes:
P55P6 - P0562 P0563 END CLEAR
Pn 34454-07E
P55P6 - 60563 END CLEAR (b0563?)
Pn 68925-07
P55P6 - 61006 61007 END CLEAR
Pn 70900069A
P55P6 - NO RSP

This is what I came up with, though I have no experience with them:
ABS
P0562 - Battery Voltage Low
P0563 - Battery Voltage High

Battery, Ignition, Lighting, Accessories
b0563 - Battery Voltage High TSM/TSSM

b1006 - Accessory Line Overvoltage
b1007 - Ignition Line Overvoltage Instruments

After reading this forum posting https://www.hdforums.com/forum/softa...e-running.html

So I believe the minimum voltage on starting tells me the battery is okay. It should be it's only a year old.

Max voltage here tells me there is no charging.
Minimum voltage starting

Maximum voltage after starting, no charging

three pin to pin tests all about 1.1-1.2 ohms.

Low resistence at plug through stator coils, and each pin to engine ground(confirmed working) were all dead shorts.

It looks like the process of elimination says likely the rectifier in the voltage regulator, or the whole thing considering the error codes pulled.

Any other ideas? My dealer is closed Mondays now so I have a day to think on this. TIA
