Service Information - Honda Transalp XL700V Manual

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 ECM. Always turn OFF the ignition switch before servicing.
• Use spark plugs of the correct heat range. Using spark plugs with an incorrect heat range can damage the engine.
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the igni-
tion switch is turned ON and current is present.
• When servicing the ignition system, always follow the steps in the troubleshooting table (page 18-4).
• The transistorized ignition system uses an electrically controlled ignition timing system. No adjustments can be made
to the ignition timing.
• 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.
• 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 plugs.
• For spark plug inspection (page 3-8).
• For CKP sensor service (page 10-12).
