IGNITION SYSTEM INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE INSPECTION
• Remove the foot board. (!7-19)
• Disconnect spark plug cap.
• With the spark plug cap connected, place a new spark plug on
the engine to ground it.
NOTE:
* Check that all the couplers are connected.
* Check that the all battery is fully charged.
Measure the ignition coil primary peak voltage using the multi
circuit tester in the following procedure.
• Connect the multi circuit tester with the peak volt adaptor as
follows.
Ignition coil: + Probe: White lead wire connector
- Probe: Ground
NOTE:
Do not disconnect the ignition coil/plug cap lead wire couplers.

Before using the multi circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
• Set the side-stand upright position, and then turn the ignition
switch to the "ON" position.
• Grasp the front or rear 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
While testing, do not touch the tester probes and
spark plugs to prevent receiving an electric shock.
If the peak voltage is lower than the specified values, inspect the
ignition coil. (!8-24)
