- Check power supply from the controller to the
ignition transformer.
- If there is no power supply, replace the main
controller.
<Fig. 2>
- If there is power supply but the ignition
transformer is not working properly, check for
coil short circuit. If the resistance shows an
infinite level, it is defective and needs to be
replaced.
