6) Insert the needle pointed probe to the lead wire
coupler.
NOTE
Use the special tool, to prevent the rubber of
the water proof coupler from damage.
7) 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.

8) Measure the ignition coil/plug cap 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.
9) 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.
Ignition coil/Plug cap primary peak voltage
80 V and more
10) After measuring the ignition coil primary peak
voltage, reinstall the removed parts.
Ignition Coil Primary Peak Voltage
Inspect the multi-circuit tester with peak voltage adaptor
as procedures:
1) Connect new spark plug to each spark plug cap and
ground them to the cylinder head.
2) Connect the multi-circuit tester with peak voltage
adaptor as follows:
#1 ignition coil:
(+) probe: Y lead wire terminal
(–) probe: Ground
#2 ignition coil:
(+) probe: G lead wire terminal
(–) probe: Ground
NOTE
Do not disconnect the ignition coil primary
wire coupler.
