Stator or Voltage Regulator?
Tried to go for a ride today and only made it about 12 miles out. The engine & battery lights came on, then off, then on, then off, then on, etc. Next thing I know I've lost my turn signals and shortly after that my speedo went to 0 and no tripometer readout. Very shortly after that the bike sputtered and quit. Ended up having it hauled home for troubleshooting.
Spent a good part of this afternoon searching the forums for helpful info which I did find and I want to make sure I'm replacing the correct part before I dig into this project.
Battery voltage tested a little low but I figured its normal for an original battery on a 2006 XL1200C. Probably time to buy a new one. Voltage went up when the bike was revved. Battery somewhat ok. Unplugged the stator from the voltage regulator and plugged in a multi-meter to the female end. My multi-meter seems to only measure AC in mV. Weird. Anyway, the guy watching the meter said it went up when I revved the motor, maybe to 100 mV. Does't look good at this point. He hooks up his multi-meter which does show AC in V. He said his went as high as 2V. Still not good. Looks like I have to replace the stator, correct? Searching the forums indicated there is no way to test the voltage regulator. So before I dig into this, does it sound like the stator to everyone?

The stator should put out 22 - 90 VAC, depending on the RPM. (22 VAC at a fast idle)
Sounds like you have a bad stator to me.
The regulator is easiest to check once the stator is working. It should convert the 22-90 VAC to an output of 13.5 - 14.8 VDC when connected to the battery.

Thanks for the quick reply. Is the 13.5 - 14.8 while the bike is running?

Ok. We were getting 12 - 12.5 VDC with the battery connected and the bike at a fast idle. Couldn't get anymore. So I'm still confused. Is the regulator at fault or the stator? One sure is easier to replace than the other.

Will do. I'll post to this thread again after the stator replacement to give everyone an update.

I recommend against using an OEM replacement. A lot of people have had bad luck with them. Use Cycle Electric Inc
