Electrical System
Digital Spark Advance Ignition (DSAI) System
This system uses a digital microprocessor which is located in ignition modules. Ignition timing varies depending upon
engine speed with this system. There are 2 inductive-style ignition modules that control ignition timing based on
engine RPM. A typical DSAI application consists of:
● 1 magnet assembly, which is permanently affixed to flywheel.
● 2 inductive, 12-volt ignition modules, which mount on engine crankcase.
● 1 12-volt battery, which supplies current to ignition modules.
● 1 kill switch (or key switch) which grounds spark advance module to stop engine.
● 2 spark plugs.
