INSPECTION OF HIGH-TENSION CORDS
1. CAREFULLY DISCONNECT HIGH-TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage
the conductor inside.
2. REMOVE llA CAP WITHOUT DISCONNECTING
HIGH-TENSION CORDS
3. INSPECT HIGH-TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance without dis-
connecting the llA cap.
Maximum resistance:
26 kfl
per
cord
If the resistance is greater than maximum, check the ter-
minals. If necessary, replace the high-tension cord and/or
llA cap.
4. REINSTALL llA CAP
5. RECONNECT HIGH-TENSION CORDS TO SPARK
PLUGS
INSPECTION OF SPARK PLUGS
1. DISCONNECT HIGH-TENSION CORDS FROM SPARK
PLUGS
2. REMOVE SPARK PLUGS
Using
SST,
remove the spark plugs.
SST 09155-16100
3.
CLEAN SPARK PLUGS
Using spark plug cleaner or wire brush, clean the spark
plug.
4. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for electrode wear, thread damage
and insulator damage.
If abnormal, replace the spark plug.
Recommended spark plug: ND
