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.
.
● The ignition timing cannot be adjusted since the ignition control module is factory preset.
● The ignition control module may be damaged if dropped. Also, if the connector is disconnected
when current is flowing, the excessive voltage may damage the ignition control module. 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.
