I have a 2000 400ex will not start I've tested all the switches and connections I have voltage going through the solenoid to the starter when I push the button and nothing happens. I know the starter is good I can hook a battery to it and it spins. I also noticed that the frame has voltage on it when I disconnected the regulator it goes away but I'm not convinced that is the problem. I took apart the wiring harness and cannot find anything out of the ordinary. Any help would be greatly appreciated!
