IGNITION COIL/PLUG CAP PRIMARY PEAK VOLTAGE
Inspect each ignition coil primary peak voltage at the ignition
coil/plug cap coupler.
• Connect the multi-circuit tester with peak voltage adaptor as
follows.
#1 ignition coil/plug cap:
W/Bl wire terminal (+ Probe) – Ground (- Probe) terminal
#2 ignition coil/plug cap:
Black wire terminal (+ Probe) – Ground (- Probe) terminal
" 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set

Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
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".
• Pull the clutch lever.
• 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.

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. (!10-27)
