My ATV has no power going to switch; replaced solenoid and still no power to start? Any suggestions how to trach power or fix the problem?

 

By "no power going to switch" have you tested the switch, or is it just that the solenoid doesn't click? I haven't got a wiring diagram for the 250 but the lockout system that prevents starting when not in neutral, is quite complex on the bigger Yams, with the neutral light circuit feeding a relay which feeds power to the start button.
