I have a 2012 Street Glide and more and more frequently my check engine and voltage lights come in when I ride. They don't come on all the time and sometimes go out after a few minutes. My voltage gage does drop to around 11 volts. I suspect the voltage regulator. Any advice will be appreciated.

 

I think you have it figured out already!

 

Before digging into the electrical, try checking the battery cable connections...both ends...for security/corrosion.

 

I was getting a number of diagnostic codes popping up on my Road King. Crank Position sensor code, high voltage code. Replaced voltage regulator and everything is back to normal.

 

Thanks to all. I just finished my test ride and all my problems are gone. The voltage regulator worked great.
