Ignition Cable: Description and Operation
Description
DESCRIPTION
Ignition cables are sometimes referred to as secondary ignition wires. The wires transfer electrical current from the electronic ignition coils to the
individual spark plug at each cylinder. The nonmetallic ignition cables have built in resistance. The cables provide suppression of radio frequency
emissions from the ignition system.
Check the ignition cable connections for good contact at the coil or coil pack and at the spark plugs. Terminals should be fully seated with audible click.
The boots should fit tightly on the coil or coil pack and fit snug around the spark plug insulators. Loose cable connections can cause ignition
malfunctions, corroding, and increasing resistance. To maintain proper sealing at the terminal connections, the connections should not be broken
unless testing indicates high resistance, an open circuit or other damage.
Clean ignition cables with a cloth moistened with a non-flammable solvent and wipe dry. Check for brittle or cracked insulation. Plastic clips in various
locations protect the cables from damage. When the cables are replaced the clips must be used to prevent damage to the cables. Then 8.4L V10 engine
requires heat shields on the ignition cable boots at the spark plugs. The heat shields should always be used when replacing or removing the ignition
cables.
