Remove the primary ignition coil wire.
Remove the ignition coil positioning bolt, and remove the ignition coil.
IGNITION COIL INSTALLATION
Reverse the removal procedure for installation.
PRIMARY IGNITION COIL INSPECTION
Standard value
0.1~1.0 k
Ω
(20
℃
)
If the resistance value is
∞
, it indicates the coil is bad and should be replaced.
SECONDARY IGNITION COIL INSPECTION
Install the spark plug cap, and measure the resistance value of the secondary ignition coil.
Standard value
7-9 k
Ω
(20
℃
)
If the resistance value is in the standard range, it indicates it is good; however,
∞
indicates the coil is bad.
Remove the spark plug cap, and measure the resistance value of the secondary ignition coil.
Standard value
2-4 k
Ω
(20
℃
)
If the resistance value is in the standard range, it indicates it is good; however,
∞
indicates the coil is bad.
The ignition coil also can be inspected and measured with the ignition testing instrument
Set the measuring switch of the ignition coil on the 1.2V position, and connect the ignition coil.
Turn the switch of the testing instrument to ON position; observe the spark over window and inspect the
spark over situation of the ignition coil. If it is a normal consistent spark, it is good; if the spark does not flash
consistently, it is not good.
