My 99 Polaris Sportsman 500 is not starting. The lights on the dash work it turns over but has no spark. There is no power going to the CDI box. It was running fine sat for 2 weeks and then this happened. Could it be just a blown fuse? Thanks in advance.

 

First thing is pull the black kill wire from the cdi module.If it still doesn't have spark you can pull the plug cap and check the bare wire against the cylinder for spark. If no spark,then pull the recoil cover and clean the face of the pick up coil and flywheel.If you still don't have spark check the resistance on the pick up coil and stator. Pick up coil white and white/red wires should be around 97 ohms. Stator red to green 1.6 ohms.Black/red to green 446 ohms. These wires lead to the cdi.
