15-18 ELECTRICAL SYSTEM
Ignition Coil Primary Peak Voltage Check
Remove the spark plug cap from the spark plug, but do
not remove the spark plug.
Install the good spark plug [A] to the spark plug cap, then
touch the frame with it.
Measure the voltage with each lead connected cor-
The correct value may not be obtained if
Maintain the correct value of compression pressure for
the cylinder (Be sure to measure the voltage with the
spark plug installed to the cylinder head.).
Connect the peak voltage adapter [B] to the digital meter.
Special Tools - Peak Voltage Adapter: 57001-1415
Needle Adapter Set: 57001-1457
Connect the peak voltage adapter to the ignition coil ter-
minal [C] and ground [D].
Ignition Coil [E]
CDI Unit [F]
Needle Adapter [G]
Shift the gear to the neutral position.
Crank the engine by kicking the pedal several times to
measure the peak voltage of the ignition coil.
Ignition Coil Primary Peak Voltage
150 V or more
Electrical equipment can cause serious electrical
shock. To avoid being shocked, do not touch the
metal portion of the probe when measuring voltage.
If the voltage is less than the specified value, see the
Engine Stop Switch System Check
Start the engine.
Push the engine stop switch [A], stop the engine.
If the engine does not stop, check the engine stop switch
for continuity (see Engine Stop Switch Inspection).
If the engine stop switch is good, check the wiring (see
If the wiring is good, replace the CDI unit.
