INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the spark plug cap 1 .
• Connect a new spark plug 2 to the spark plug cap and
ground it on the cylinder head.
NOTE:
Make sure that the spark plug cap and spark plug are connected
properly.
Measure the ignition coil primary peak voltage using the
multi-circuit tester in the following procedure.
• Connect the multi-circuit tester with the peak volt adaptor as
follows.
+ Probe: Black/White lead wire
- Probe: Black/Yellow lead wire
NOTE:
Do not disconnect the ignition coil lead wires.
09900-25008: Multi-circuit tester set
Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
• Turn the ignition switch to the "ON" position.
• Push 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
highest ignition coil primary peak voltage.
Tester knob indication: Voltage (
Ignition coil primary peak voltage: 150 V and more
While testing, do not touch the tester probes and
spark plug to prevent receiving an electric shock.
If the voltage is lower than the specified values, inspect the igni-
tion coil. ( 6-19)
