I have a 2011 polaris ranger 400. With the motor running and i switch the headlights on, the motor cuts out and then continues to run. If the motor is warm it doesn't kill the motor it's almost like you cut the key off and back on very quickly, it may backfire if you're running down the road at high rpms. When you flip the headlights on they initially blink and then work perfectly. I noticed the ignition switch was loose so i tightened it up. I pulled the fuse on the headlights and tail lights and it will still do it. I also noticed that when the key is in the headlights on position you can wiggle the key(it has a little slack in it) and i can make the problem occur that way. I am hoping that a new ignition switch will cure the problem but i just wanted to see if anyone here had any input.
