One step at a time - is there power on the red wire going to the key switch? If no, you have a bad battery, connection or circuit breaker - if yes, is there power on the red/black wire at the LH handlebar control? If no, you have a bad connection at the key switch, a bad key switch or a broken wire between the key switch and the LH handlebar control? If yes, is there power on the red/white wire out of the handlebar switch? If yes, then check for power on the red/wht wire at the accessory plug and all the other red white wires you can find (not the white/red wire) most likely the red/wht wire is broken between the switch and one of the splices where the red/white wire branches off to other components.
