if that doesnt work, then you will need to check the sensor inside of the belt cover. on the other side of that sensor is a switch that can be tripped. it will need to be in the ON position. if that doesnt work or nothing is found with that either, then you will need to get in contact with you local arctic cat dealership to see if your atv falls under a recall. there was a recall put out that the CDI creates voltage spikes that cause the light to come on.
