INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE

• Remove the front fender, ( d r * 7-6)
• Remove the spark plug cap.
• Connect a new spark plug to spark plug cap and ground it to
the cylinder head.
NOTE:
Make sure the spark plug cap and spark plug are connected
properly and the battery is fully-charged.
Measure ignition coil primary peak voltage using the multi cir-
cuit tester in the following procedure.
• Connect the multi circuit tester with the peak voltage adaptor
as follows.

When using the multi circuit tester and peak volt
adaptor, refer to the appropriate instruction manual.
• Shift the transmission into neutral and turn the ignition switch
to the "ON" position.
• Press the starter button and allow the engine to crank for a
few seconds, 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.
Tester knob indication: Voltage
Ignition coil primary peak voltage: More than 140 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. {czr 8-21)
