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

(impedance 10 M lli DCV minimum)
CONNECTION:
Blue /ye ll ow terminal 1+1 - Green I-l
Shi ft the transmission into neutral.
Crank
the engine with the kickst arter and read the

PEAK VOLTAGE: 0.7 V minimum
leM CONNECTOR
If the peak vo lt age measured at leM connector is r iGNrnclNPlJUiEZ.];iffi;;:;miCmmECTc;;-l
abnormal, measure the peak vol tage 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 manne r 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 ir e harness has an
open circuit,
or loose connection.
• If both peak voltages are abno r mal, fo ll ow the
checks described
in the troubleshooting chart
(page 14-4).
