IGNITION SYSTEM
GENERAL
The vehicle uses a breakerless inductive-discharge ignition
system. The system has both a primary and secondary cir-
cuit. The primary circuit consists of the battery, ignition switch,
primary coil winding, computerized ignition timer and associ-
ated wiring. The secondary circuit consists of the secondary
coil, spark plugs and associated wiring. See Figure 7-1.
The computerized ignition system contains three assemblies.
Ignition Module
The ignition module is mounted to the vehicle frame under a
protective cover; it is located to the right of the battery. The
ignition module has two functions. First, it computes the spark
advance for proper ignition timing. Second, it opens and
closes the low-voltage circuits between the battery and igni-
tion coil to produce high-voltage discharge to the spark plugs.
