Ignition System: Description and Operation

The electronic ignition system consists of a distributor assembly, a coil, four spark plugs and high tension leads. Spark timing varies to suit engine operating conditions.
The distributor is mounted on the rear surface of the cylinder head and is driven directly off the end of the camshaft. Ignition timing is modified by the electronic control assembly (ECA). Based on inputs from the barometric pressure sensor (BP), at altitudes of 3280 ft or higher, the ECA will signal the ignition module to advance ignition timing.
The ignition coil is entirely molded in resin and is mounted to the air cleaner housing.
