I have a 1988 force 125 that started performing poorly upon trouble shooting I found the #3 cylinder did not have spark (checked with spark plug test light)I disconnected the coil for the number3 cal and swapped the coil with the #4 cal and connected both which resulted in the #3 having spark and the #4 not having spark. fast foward to now and the motor just Burt out its fourth coil in 3 seasons. since its the same cylinder and the battery is charging correctly im leaning towards a bad stator or trigger? I was going to change both and the coil until I saw the price of the parts. I don't see any wires chaffed or loose and when all 4 cal are working the motor perform flawlessly. Is it usually the stator or the trigger that goes bad and how and what are the parameters for both im assuming I would be checking resistance and/or continuity just don't know where to test with a meter
