INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
Remove the fuel tank. (
Remove the spark plug cap and spark plug.
Connect a new spark plug to the spark plug cap and ground it
to the cylinder head.
NOTE:
Make sure that the spark plug cap and spark plug are connected
properly.
Do not let the spark plug touch the cylinder head cover,
otherwise the cylinder head cover may be damaged.
Measure ignition coil primary peak voltage using the multi circuit
tester in the following procedure.
Connect the multi circuit tester with the peak voltage adaptor
as follows.
Ignition coil:
Black/White terminal – Black/Yellow
(+ probe)
NOTE:
Do not disconnect the ignition coil primary wire.
09900-25008: Multi circuit tester set
Before using the multi circuit tester and peak volt adap-
tor, be sure to refer to the appropriate instruction manual.
Shift the transmission into neutral, and then turn the ignition
switch to the "ON" position.
Pull the clutch lever.
Press the starter button and allow the engine to crank for a few
seconds, and then measure the ignition coil primary peak volt-
age.
Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage.
Tester knob indication: Voltage (
Ignition coil primary peak voltage: More than 150 V
While testing, do not touch the tester probes and spark
plug to prevent receiving an electric shock.
If the voltage is lower than the specified values, inspect the igni-
tion coil. ( 7-22)
