18. IGNITION SYSTEM K-XCT 125i
SERVICE INFORMATION
GENERAL INSTRUCTIONS
Some electrical components may be damaged if terminals or connectors are connected or
disconnected while the ignition switch is "ON" and current is present.
When servicing the ignition system, always follow the steps in the troubleshooting..
The ignition control module or ECU may be damaged if dropped. Also, if the connector is
disconnected when current is flowing, 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 results
in a slower engine cranking speed as well as no spark at the spark plug.
Use a spark plug of the correct heat range. Using spark plug with an incorrect heat range can
damage the engine.
