okay. I have a new battery, new starter, new starter solenoid and my ATV still will not start when I hit the switch. Therefore, I assume the problem is in my switch. I can jump the starter solenoid it will crank right up. Does anyone know how to troubleshoot the switch or know what other things to look for? Thanks.

 

have you taken it apart to clean the coctact points? might be just corroded.

 

Check to see if the solenoid is getting a signal from the switch. Put a volt meter on the solenoid where it comes from the starter, should be one of 2 of the smaller lugs on the solenoid. Hit the starter button and see if anything registers. A wiring diagram will be very helpful as well. Let me know if you need one.
