I have been working on a 1998 Honda 250 TRX which was brought to me with no spark, it just quit one day while it was sitting still, idling. I have exhausted everything that I know how to do it fix the problem. I have replaced the coil and CDI box which had been replaced by the owner before. I have ohmed every wire in the ignition system. I have replaced the stator and the exciter coil, and again the exciter coil again after finding the aftermarket part had to short of a terminal and the wire fell off of it, after it ran for about a minute, I then checked it for spark, which was not present, flipping the kill switch back and forth made the spark return, so I replaced the kill switch assembly, still no spark. In checking the voltage at the exciter wires, there is no voltage present. Checking the voltage from the stator at the CDI unit shows approximately 140 volts. Checking the voltage at the coil primary shows no voltage present. Disconnecting the neutral switch dosen't help either. I again removed the stator housing, and again checked it's wiring and found nothing. Is it possible that the flywheel somehow became demagnatized or that the gap between the flywheel and the pickup is not right? I am a car guy, former ASE and I just can't figure this one out. Need help from someone who is better then I am, please?
