INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
• Disconnect the spark plug cap.
• Connect a new spark plug 1 to spark plug cap and ground it
to the cylinder head.
NOTE:
Make sure that the spark plug cap and spark plug are connected
properly and the battery is fully-charged.
Measure ignition coil primary peak voltage using the multi-circuit
tester in the following procedure.
• Connect the multi-circuit tester with the peak voltage adaptor
as follows.
+ Probe: Black/White lead wire or ground
- Probe: Black lead wire
NOTE:
Do not disconnect the ignition coil primary wires.
09900-25008: Multi-circuit tester set
When using the multi-circuit tester and peak volt
adaptor, 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. If the voltage is
lower than the standard values, inspect the ignition coil.
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.
