IGNITION SYSTEM
IGNITION PULSE GENERATOR PEAK
VOLTAGE
Check that the cylinder compression is normal and the
spark plug is installed correctly in the cylinder head.
Disconnect the ignition control module (ICM) connector
(page 16-6).
Connect the peak voltage adaptor probes to the ignition
pulse generator wire and ground wire terminals of the
wire harness side connector.
ICM 10P CONNECTOR
IGNITION PULSE GENERATOR
CONNECTOR
CONNECTION:
Blue/Yellow wire terminal (+) — green wire
terminal (–)
Turn the ignition switch ON.
Crank the engine with the kickstarter and read the peak
voltage.
PEAK VOLTAGE: 0.7 V minimum
If the peak voltage measured at the ICM connector is
abnormal, disconnect the ignition pulse generator
connector and connect the adaptor probles to the ignition
pulse generator side connector.
In the same manner as the ICM connector, measure the
peak voltage and compare it to the voltage measured at
the ICM connector.
• If the peak voltage measured at the ICM connector is
abnormal and the one measured at the ignition pulse
generator connector is normal, the blue/yellow wire
has an open or short circuit, or loose connections.
• If both peak voltages are abnormal, follow the checks
described in the troubleshooting on (page 16-2).
