Ignition System: 1H-8
5) Insert the needle pointed probe to the lead wire
coupler.
CAUTION
!
Use the special tool to prevent the rubber of
the water proof coupler from damage.
6) Connect the multi-circuit tester with the peak voltage
adaptor as follows.
CAUTION
!
Before using the multi-circuit tester and peak
voltage adaptor, refer to the appropriate
instruction manual.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
(B): 09900–25009 (Needle pointed probe
set)
Tester knob indication: Voltage ( )
7) Measure the ignition coil primary peak voltage in the
following procedures:
WARNING
!
Do not touch the tester probes and spark
plugs to prevent an electric shock while
testing.
a) Shift the transmission into neutral, turn the
ignition switch ON and grasp the clutch lever.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
ignition coil primary peak voltage.
8) Repeat the b) procedure several times and measure
the highest peak voltage.
If the voltage is lower than standard range, inspect
the ignition coil/plug cap and the CKP sensor.
Ignition coil primary peak voltage
80 V and more
9) After measuring the ignition coil primary peak
voltage, reinstall the removed parts.
