Just bought a 2012 F650GS Twin but can't seem to get any life from the Aux power socket. It won't accept my charger through the socket and I have tried connecting a bulb across the wires from the plug but all appears dead, So I've been searching for the 5amp fuse but cannot find a fuse box and the riders handbook gives no clues as to location? Anyone able to give me some advice? Would it be best to fit some wire connectors to the battery terminals and just plug in my charger to the leads or is that not recommended? I use a top dog charger for AGM sealed batteries made by CTek 0.8/5.0amp charge rate.
