ELECTRICAL SYSTEM 8-19
INSPECTION
IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the fuel tank cover. (!7-5)
• Remove the spark plug cap.
• 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 and the battery is fully-charged.
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.
+ Probe: Black/White lead wire or Ground
- Probe: White/Blue lead wire
NOTE:
Do not disconnect the ignition coil primary wire.

• Shift the transfer to the neutral position 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 150 V
1
If the voltage is lower than the standard values, inspect the igni-
tion coil. (!8-20)
When using the multi circuit tester and peak volt adap-
tor, refer to the appropriate instruction manual.
While testing, do not touch the tester probes and
spark plug to prevent receiving an electric shock.
