ELECTRICAL SYSTEM 6-23
INSPECTION
IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the leg rear shield. (!5-8)
• Remove the spark plug cap.
• Connect a new spark plug to the spark plug cap and ground it
to the cylinder head cover.
NOTE:
Make sure that the spark plug cap and spark plug are connected
properly.
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
- Probe: White/Blue lead wire
NOTE:
Do not disconnect the ignition coil lead wires.

• Turn the ignition switch to the “ON” position.
• Squeez the brake lever.
• 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: 150 V and more
0
If the voltage is lower than the specified values, inspect the igni-
tion coil. (!6-24)
Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
