Many times, when the handlebar control covers are removed, the wires will get pinched when they are reinstalled. Eventually the wire grounds out on the bars & pops a fuse. This happened on mine several times & took out the cruise, headlight, & turn signals. The first time it happened the fuse still looked good to the eye, but when I put a multi-meter on it I found it to be bad.
Other than checking the CC fuse with a meter, I've run out of ideas. Sorry, best of luck getting it figured out.
