4. DISASSEMBLING AND SERVICING
Check the ignition coil
（primary side）
Measure the resistance of the primary coil by attaching one
ohmmeter lead to the ignition coil’s primary terminal while
touching the other tester lead to the iron core
Primary side resistance value：1.1-1.3Ω
（Secondary side）
Measure the resistance of the secondary side of the coil with
the spark plug cap removed, touching one test lead to the
high tension cord while touching the other tester lead to the
coil’s iron core.
Secondary side resistance value：10.6-11kΩ
Spark plug cap
Measure the resistance of the spark plug cap by attaching
one ohmmeter lead to the wire end of the plug cap while
touching the other tester lead to the spark plug end.
Resistance value：4.5-5.5kΩ
