symptoms: key on, all lights etc come on, but no sound or activity when starter pressed. It seems no signal is being sent to the relay to start. tests: bike in neutral kill switch disabled battery = good ( brand new ) fuses = good starter works and bike starts when shorting across the starter relay. clutch switch removed ignition switch replaced starter relay replaced what other tests should i be running? Im about to start checking all the wires for a stray short. Where should i be checking for a good earth? the coil under the tank? its an sm model that has a tilt sensor right? could that be faulty? thanks for your time _sam
http://imgur.com/IWVbt7z if anyone else gets the same issue the problem in my case was a broken wire right in the middle of the wire harness as it passes under the tank. you can see the green/ white wire is severed. it carried the positive signal from the ignition switch directly to the starter relay. Once i figured out the wiring diagram it was super simple. hope that helps someone. _sam
indeed, the green/white is the critical starter wire, red/green is the horn. ill fix it too, heres hoping the whole lot arent about to go. its an area that sees a lot of flex. what would be the best solution here? add a new section of wire and make the joins either side of this high flex zone?
