buell s1 lightning '97 Manual

 

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 

The computerized ignition system contains three assemblies.

 

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.
