SPARK PLUG CAP INSPECTION
Measure the resistance of the spark plug cap [1] by
attaching one ohmmeter probe to the terminal in the
spark plug cap and the other to the high-tension cord
terminal.
RESISTANCE: 7.5 – 12.5 kΩ (20°C/68°F)
If measured resistance is out of specification, replace
the spark plug cap.
IGNITION COIL INSPECTION
Remove the fan cover (page 5-2).
PRIMARY SIDE
Disconnect the ignition coil connector [1].
Measure the resistance of the primary coil by attaching
one ohmmeter probe to the terminal [2] and the other at
the iron core [3].
RESISTANCE: 0.68 – 0.92 Ω
If measured resistance is out of specification, replace
the ignition coil.
SECONDARY SIDE
Disconnect the spark plug cap from the high-tension
cord [1].
Measure the resistance of the secondary coil by
attaching one ohmmeter probe to the high-tension cord
and the other at the iron core [2].
RESISTANCE: 5.6 – 8.4 kΩ
If measured resistance is out of specification, replace
the ignition coil.
