Ignition Cable: Description and Operation
SECONDARY WIRINGThe spark plug wiring used with the ignition system is a carbon impregnated cord conductor encased in an 8 mm (5/16 inch) diameter silicone rubber jacket. The silicone wiring will withstand very high temperatures and also provides an excellent insulator for the high voltage of the ignition system.
NOTE: The silicone spark plug wire assembly boot forms a tight seal on the spark plug assembly. The boot should be twisted 1/2 turn before removing. DO NOT pull on the wire assembly to be removed. Pull on the boot or use a tool designed for this purpose.
