SPARK PLUG CABLE 7.10
GENERAL
Resistor-type high-tension spark plug cables have a carbon-
impregnated fabric core, instead of solid wire, for radio noise
suppression and improved reliability of electronic compo-
nents. Use the exact replacement cable for best results.

WARNING
Never disconnect the spark plug cable with the engine
running. If you disconnect the spark plug cable with the
engine running, you may receive a severe electric shock
from the ignition system which could result in death or
serious injury.
IMPORTANT NOTE
When disconnecting the spark plug cable from its spark
plug terminal, always grasp and pull on the rubber boot
at the end of the cable assembly (as close as possible to
the spark plug terminal). Do not pull on the cable portion
itself. Pulling on the cable will damage the cable’s carbon
core.
Disconnect spark plug cable from ignition coil and spark plug
terminal. Inspect removed cable for damage.
INSPECTION
1. See Figure 7-28. Inspect spark plug cable. Replace
cable if worn or damaged.
a. Check for cracks or loose terminals.
b. Check for loose fit on ignition coil and spark plug.
2. Check cable boot/cap for cracks or tears. Replace boot/
cap if worn or damaged.
3. See Figure 7-29. Check spark plug cable resistance with
an ohmmeter. Replace cables not meeting resistance
specifications of 2375-5833 ohms.
INSTALLATION
1. Connect spark plug cable to ignition coil and spark plug.
2. Fasten boot/cap securely. Tight connections provide the
necessary moisture-proof environment for the ignition
coil and spark plug terminals.
