I noticed one rear LED bulb was out and since they last years I knew it was an electrical problem - no power to socket (and note the sockets tend to split so one wire is not contacting the outside) so took off the rear brake light mount - no power inside that.
Knew its got to be under the GD fender so have to remove saddle bags and seat and rear fender bolts and turn it over and - ta da Even though the damn wire bundle is well fastened to the underside one small section was low enough so that on a bump it hit the rear wheel and you can see what it did 0 will re-solder a piece of wire in side the bundle and put one of those plastic coil wrap things around it and zip=lock it all up out of the way
