IGNITION SYSTEM
17-3
SERVICE INFORMATION
GENERAL
• The ECM may be damaged if dropped. Also if the connector is disconnected when current is flowing, the excessive volt-
age may damage the module. Always turn off the ignition switch before servicing.
• Use spark plug of the correct heat range. Using a spark plug with an incorrect heat range can damage the engine.
• When servicing the ignition system, always follow the steps in the troubleshooting table (page 17-4).
• The transistorized ignition system uses an electrically controlled ignition timing system. No adjustments can be made
to the ignition timing.
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the igni-
tion switch is ON position and current is present.
• A faulty ignition system is often related to poorly connected or corroded connections. Check those connections before
proceeding.
• The ECM varies ignition timing according to the engine speed. The TP sensor signals the ECM to compensate the igni-
tion timing according to the throttle opening.
• 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.
• For CKP sensor service (page 17-6).
• For ECM service (page 5-66).
• Refer to following components informations:
– Diode (page 18-15)
– Ignition switch (page 19-13)
– Engine stop switch (CM and U type) (page 19-14)
– Neutral switch (page 19-17)
– Sidestand switch (page 19-19)
– Clutch switch (page 19-20)
