I have a 2002 Polaris magnum 325, The other day I went to use it and it went dead all of a sudden. There is no power to the gear selector lights or to the starter. But when i turn the key on the lights come on. When i turn to crank it nothing happens, i've tried a new starter solenoid, new ignition and cleaned battery posts. The fuse that is inside of the black bag on the frame of the quad is good. Any ideas?

Thanks that helped! it was the connection between the handlebar controls and the wiring harness plug that was dirty and not getting power.

 

Common problem on the two connectors and pins on the left control switch that people over look. Some connectors would lose contact and pull back a little over time from vibration also.To solve that you can use a strip of electrical tape at the top of the connector to make it fit tighter in the switch after you use a dab of electrical grease on the pins.Had a couple customers use that fix.
