• Check cylinder compression and check that the ~------------------,
spark plug is installed correctly.
Remove the seat assembly (page 2-3).
Disconnect the 4P connector from the leM.
Connect the pea k voltage adaptor or peak voltage
tester probes to t he connector t erminals of the wire
harness side.
TOOLS:
Peak vottage tester

Shift the transmission into neutral.
Crank the engine with the kickst arter and read the

leM CONNECTOR
If the peak voltage measured at leM connector is
riGNrnclNPlJUiEZ.];iffi;;:;miCmmECTc;;-l
abnormal, measure the peak volt age at the pulse IGNITION PULSE GENERATOR
generator connector.
Disconnect the ignition pulse generator connector
(Blue/yellow) and connect the peak voltage adaptor
or tester probes to the connector terminal of the
ignition pulse generator side and ground.
In the same manner as at the leM connector, mea~
sure the peak voltage and compare it to the voltage
measured at the leM connector.
• If
the peak voltage measured at the leM is abnor-
mal and the one measured at the ignition pulse
generator is normal, the w ire harness has an
open circuit, or loose connection.
• If both peak voltages
are abnormal, fo llow the
checks described in the troubleshooting chart
(page 14-4).
