I have a 2010 Ultra Classic and on a recent trip I had a strange problem with the cruise control. While riding and cruise control set the cruise would just shut off ( green indication to red/orange ) and it would not activate. however, every time after a stop to refuel and back on the road it would work for a random amount of time and mileage. It ranged anywhere from 20 minutes to several hours. Another thing I noticed is that the the sixth gear indicator light on would also go out every time and not return until after a fuel stop. There appears to be a link but I, not sure if one is causing the other. While it was working I could set the cruise in other gears as long as I was going the minimum speed. Anyone have any thoughts ?

 

Do you have a power commander v on your bike? If you do you need to hook a compter up to it and disable the diagnostics. Do a search on hd forums and there is a post explaining it. check this out

Does your bike have a PCV. If so there is a known firmware issue but also a workaround. You will need a laptop , power commander software from DynoJet's website, and USB cable to access the PCV. Perform the following:
1) In the Power Commander software go to Power Commander Tools/Configure/Harley ECM Data. Uncheck the box next to Diagnostic Port Enabled.
2) Click OK.

3) Click Send Map.
I had the same issue after installing a PCV during a stage 1 upgrade. This fixed my issue.
