  If the ignition system of your ATV Offroad Vehicle isn't working, try these steps: Replace the spark plug, spark plug cap, ignition coil, handlebar switch (left), main switch, triggering coil, or charge coil. Also, ensure the ignition system is correctly connected and replace the CDI assembly if necessary.
