I have 2009 xb12r and I am trying to figure out what is wrong with the charging system. I have measure voltage at battery while running only 12v and reving only 12v. So then I pulled the the stator plug and measured a resistance of 0.3 ohms between the pins. Measured to ground there was no continuity. So then I measured AC volts arcoss the stator while running and measured 22vac at idle and went up with higher rpms. Next I checked the voltage regulator housing to ground and measured o.1 ohms. I then measured DC voltage across the 2 leads coming from the voltage regulator and it was reading 35vdc.



Is the VR bad or am i doing something wrong?



Also found this problem the other day while riding the check engine light came on. Stopped for gas and didnt have enough juice to start back up.
