IGNITION SYSTEMS
Turn the ignition switch ON. If equipped with an engine stop switch, turn
it
to RUN position. In case of transistorized ignition
system, then measure the voltage (initial voltage). If the tester indicates a value close to the battery voltage, the ignition coil
power supply circuit is normal. If there is no voltage, the power supply circuit is defective. Check each item referring to the
troubleshooting chart. Messure the peak voltage of the ignition coil primary side with the ignition switch ON and the engine
stop switch to RUN position, while cranking the engine with the kick starter or starter motor. Refer to the Model Specific
manual for the peak voltage value.
NOTE
If there are connectors between the ignition control module and the ignition coil, it is possible to check an open circuit
or poorly connected connectors by comparing the peak voltage measured at every points. If no defects are found in
the harness after checking it completely, the peak voltage is abnormal.
In case of a configuration where several ignition coils are driven by one ignition control module, disconnected or loose
connection in another ignition system circuit may cause abnormal voltage readings.
On the models which use t w o or more ignition coils, various voltage may differ. As long as the measured voltages ex-
ceed the specified value, the system is normal.
