INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
Remove the fuel tank. (
Remove the spark plug cap and spark plug.
Connect a new spark plug to 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
When using the multi circuit tester and peak volt adap-
tor, refer to the appropriate instruction manual.
Shift the transmission into neutral and set the engine stop
switch to the "RUN" position.
Pull the decompression lever.
Kick the kick starter lever and allow the engine to crank for a few
times, and then measure the ignition coil primary peak voltage.
Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage.
NOTE:
Be sure to remove the spark plug, first, and then kick the kick
starter lever.
Kick the kick starter lever as usual.
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 standard values, inspect the igni-
tion coil. ( 7-20)
