I have an 03 400EX that will not start by the push button. However you can roll it off or cross solenoid over and it will fire right up. I have installed new battery,solenoid,and rectifier. I have also search the wiring harnesses and cant find any loose wires or bad connections. I found that if you take plug off the rectifier and cross two of the wires that go into that plug that the push button then works. I also do not have any lights working on it. No headlights, brake light or the neutral light. Could anyone be of assistance with this?
