To avoid possible electrical shock duríng voltage meas-
urements, do not touch test probe metal parts.
If the peak voltage measured at the CDI unit connector is ab-
normal, disconnect the pulse generator wire
3P
connector and
connect theadaptor probes to the pulse generator (blue/yel-
lowl wire terminal and body ground.
In the same manner as atthe CDI unit connector, measure the
peak voltage and compare it to the voltage mea su red at the
CDI unit connector.
If the peak voltage measured at the CDI unit is abnormal
and the one rneasured at the pulse generator is normal, the
wire harness has an open circuit or loase connections.
If both peak voltages measured are abnormal, check each
item in the troubleshooting chart. If all items are normal,
the pulse generator is faulty.
Ignition Coil
Inspection
Remove the fuel tank (page 2-4l.
Disconnect the ignition coil primary terminals and measure the
primary coil resistance of the ignition coil.
Standard:
0.1-0.3

(20°C/68°¡;¡
Disconnect the spark plug caps from the spark plug and meas-
ure the secondarv coil resistance between the ignition coil
green wire terminal and spark plug cap.
