Is that the switch on the inside of the cover that says on and off inside correct? Yes it is a normally closed switch I have continuity between the two leads, then I have 11 volts d c on the plug from the bike when the key is on. The dealer said it is a sensor that is telling the quad that the belt is worn or no good, and it is cutting the quad out. Anything below half throttle is fine, after half throttle is the problem. The dealer said it is one of two sensors but they also said its crazy to change both of them because they are very expensive. I have a video of what it's doing but I am new to these forums and don't know how to post it, if someone can walk me through posting it I would appreciate it or I can email it to you.
