Hello I know I started this topic before but I have lost it. So here is the story, I bought this XLT 500 earlier this year it is was and still is in rough shape the ID plate is gone, faded paint, bad window, etc... When I got it, it ran rough and the all of a sudden it quit running. So I started looking into it and found no spark. No biggie changed plug, and coil, still nothing. So went and replaced the coil wire, still nothing. So I have gone pretty far now. I have replaced the stator magneto, the voltage regulator, CDI, I do have the crank shaft position sensor but have never figured out where it goes have been told around the stator but have yet to find it. Have chased wire out and still nothing. At the coil I have one wire giving good voltage the other one nothing, and when you crank it the voltage goes all over the place. So besides the key I have changed every part that has to do with the starting that I can find. So information on what I am missing or doing wrong would be great, it acts like the kill switch on the brakes is stopping it from starting, however I have bypassed that to make sure that was not the problem and still nothing. So aside of parking this thing in the back and letting it die a slow death I am at a loss on what to do next, Help!
