SPARK PLUG CABLES
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.
REMOVAL
1WARNING
Never disconnect a spark plug cable with the engine run-
ning. If you disconnect a spark plug cable with the
engine running, you may receive a potentially fatal elec-
tric shock from the ignition system.
1CAUTION
When disconnecting each 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 possi-
ble 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 cables from ignition coil and spark plug
terminals.
INSPECTION
1. Inspect spark plug cables. Replace cables that are worn
or damaged.
a. Check for cracks or loose terminals.
b. Check for loose fit on ignition coil and spark plugs.
2. Check cable boots/caps for cracks or tears. Replace
boots/caps that are worn or damaged.
3. Check spark plug cable resistance with an ohmmeter.
Resistance must be 1625-3796 ohms for 6-1/2 in. (165
mm) cable, and 5000-11,680 ohms for 20 in. (508 mm)
cable. Replace cables that do not meet resistance speci-
fications.
INSTALLATION
Connect spark plug cables to ignition coil and spark plugs.
Make sure boots/caps are secured properly; this will provide
the necessary moisture-proof environment for the ignition coil
and spark plug terminals.
NOTE
See Section 1 for spark plug information.
