I own a 2005 Yamaha yfz 450se I was riding everything was fine shut it off then went to start it turned the switch to run and the ignition on pushed the start button and nothing no neutral light or headlights. I have power going thru the off on switch power going thru the key. Tried with the clutch in and out it is in neutral. There is a black and a blue wire that go to the start button itself does anyone know if the black is a ground wire. Would a bad natural relay switch cause this.
