Electronic Ignition System with Spark Advance (Smart Spark
™
), CV16 Engines
The CV16 engines are equipped with an electronic
capacitive discharge ignition system with electronic
spark advance. A typical application (Figures 8-5 and
8-6) consists of the following components.
• A magnet assembly which is permanently affixed
to the flywheel.
• An electronic, capacitive discharge ignition
module which mounts on the engine crankcase.
• A spark advance module which mounts to the
engine shrouding.
• A 12 volt battery which supplies current to the
spark advance module.
• A kill switch (or key switch) which grounds the
spark advance module to stop the engine.
• A spark plug.
