ELECTRICAL SYSTEM 13-15
Ignition Coil Primary Peak Voltage Check
Disconnect the spark plug cap from the spark plug [A].
Connect the new spark plug [B] to the spark plug cap,
then ground it to the engine.
Measure the voltage with each lead connected c or-
rectly. The correct value may not be obtained if
Maintain the correct value of compression pressure for
the cylinder. (Be sure to measure the voltage with the
spark plug installed to the cylinder head.)
Connect the peak voltage adapter [A] between the termi-
nal of primary lead (orange) and ground connection of the
lead of the ignition coil [B].
Special Tool - Peak Voltage Adapter: 57001-1415
Hand Tester: 57001-1394
Tester Positive → Ground Lead [C]
Tester Negative →Orange Lead [D]
Shift the gear to the neutral position, then push the engine
Crank the engine by kicking the pedal several times to
measure the peak voltage of the primary ignition coil.
DC 115 V or above
Do not touch the metal portion of the probe in case
of measuring the voltage, or you may receive a se-
rious electric shock.
If the voltage is less than the specified value, see the next
