Ignition Cable: Description and Operation
Spark Plug cables are sometimes referred to as secondary ignition wires. The wires transfer electrical current from the electronic ignition coils to the
individual spark plugs at each cylinder. The nonmetallic spark plug cables have built in resistance. The cables provide suppression of radio frequency
emissions from the ignition system.
Check the spark plug cable connections for good contact at the coil and at the spark plugs. Terminals should be fully seated with audible click. The
nipples and spark plug covers should be in good condition. Nipples should fit tightly on the coil and spark plug cover should fit tight around spark plug
insulators. Loose cable connections can cause ignition malfunctions by permitting water to enter the towers, 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 high tension cables with a cloth moistened with a non-flammable solvent and wipe dry. Check for brittle or cracked insulation.
