9-26 ELECTRICAL SYSTEM
NOTE:
Use the special tool, to prevent the rubber of the water proof
coupler from damage.
• Shift the transmission into neutral and turn ignition switch
"ON".
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the ignition coil primary
peak voltage.
• Repeat the above inspection a few times and measure the
highest peak voltage.
 Tester knob indication: voltage ()
 Ignition coil primary peak voltage: 80 V and more

Do not touch the tester probes and spark plugs to pre-
vent an electric shock while testing.
If the peak voltage is lower than the standard range, check the
ignition coil/plug cap as follow.
IGNITION COIL/PLUG CAP RESISTANCE
• Check the ignition coil/plug cap for resistance in both primary
and secondary coils. If the resistance is not within the stan-
dard range, replace the ignition coil/plug cap with a new one.
