INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the fuel tank. (
• Disconnect the four spark plug caps.
• Connect new four spark plugs to each spark plug cap and
ground them to the ignition coil brackets.
NOTE:
Make sure that all couplers and spark plugs are connected prop-
erly and the battery used is in fully-charged condition.
Measure the No. 1 & 4 and No. 2 & 3 ignition coils primary peak
voltage in the following procedure.
• Connect the multi circuit tester with peak voltage adaptor as
follows.
No. 1 & 4 ignition coil: + Probe: White/Blue
- Probe: Orange/White
No. 2 & 3 ignition coil: + Probe: Black
- Probe: Orange/White
NOTE:
Do not disconnect the ignition coil primary wire coupler.
09900-25008: Multi circuit tester set
Before using the multi circuit tester and peak volt adap-
tor, be sure to refer to the appropriate instruction manual.
• Shift the transmission into the neutral and then turn the ignition
switch to the "ON" position.
• Pull the clutch lever.
• Press the starter button and allow the engine to crank for a few
seconds, and then measure the ignition coil primary peak volt-
age.
• Repeat the above procedure a few times and measure the high-
est ignition coil primary peak voltage.
Tester knob indication: Voltage (
Ignition coil primary peak voltage: More than 150 V
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. ( 7-21)
