Ignition System: Service Precautions
Compression ChecksWhen making compression checks, disconnect the ignition coil connector. To prevent damage to the locking tab on the ignition coil, do not use a screwdriver to release the locking tab.
Spark Plug Wires
The material used to construct the secondary (spark plug) wiring is very soft. This allows the wiring to withstand more heat and carry a higher voltage than traditional wiring; however, the wire is more susceptible to scuffing and damage. The secondary wires must he routed correctly to prevent chafing or cutting. When removing a secondary wire from a spark plug, a distributor or an ignition coil, twist the boot one-half turn and pull on the boot only.
