18. IGNITION SYSTEM
15-3
DINK 200i/125
SERVICE INFORMATION
GENERAL INSTRUCTIONS
Some electrical components may be damaged if terminals or connectors are disconnected while the
ignition switch is “ON”.
● When servicing the ignition system, always follow the steps in the troubleshooting.
● The ignition timing cannot be adjusted since the ignition control module is set by factory preset.
● The ignition control module or ECU may be damaged if battery’s power dropped. Also, if the
connector is disconnected when current is working, the excessive voltage may damage the
ignition control module or ECU. Always turn off the ignition switch before servicing.
● A faulty ignition system is often related to poor connections. Check those connections before
proceeding.
● Make sure the battery is adequately charged. Using the starter motor with a weak battery can
result in a slower engine starting speed as well as no spark at the spark plug.
● Use of spark plug with improper heat range is the main cause of poor engine performance.
● Check the ignition system according to the sequence specified in the Troubleshooting.
