14-114. IGNITION SYSTEMSERVICE INFORMATIONGENERAL SAFETY● Refer to the malfunction diagnosis when inspecting ignition devices.● Because the ignition devices have installed electrical advancer devices, it is impossible to adjust ignition timing.● Be careful when handling the ignition devices as they can become easily damaged if dropped or bumped. Also, do notdisconnect or connect the connectors and couplers when the main swtich is turned ON as excessive electric current cancause damage in the unit. Always perform maintenance work on the ignition devices with the main switch turned OFF.● Ignition devices can often appear to be malfuctioning when the couplers or connectors are disconnected. Check theseconnections before working on.● Use recommended spark plug. Using incorrect spark plug may make the engine run badly or damage the engine.● This manual gives explanations on inspections to receive peak voltage. As inspections for coil resistance values are alsoincluded, it may be difficult to make a correct determination.● Conduct inspection on the main swtich by referring to the wiring diagram continuity chart.
