Section 05 ELECTRICAL Subsection 02 (OVERVIEW)
IGNITION SYSTEM
An CDI (Capacitor Discharge Ignition) system is utilizedThe ignition system is made up of the following components:
Magneto FlywheelTrigger Coil
The magneto flywheel features two protrusions that are working with the trigger coilThe trigger coil sends the signals to the electronic module to be processed for the ignition system
Single-Spark Ignition CoilSpark Plug
The single-spark ignition coil (stick coil) receives its signal from the electronic moduleThe stick coil steps up the input voltage and the end result is firing of the spark plug
Electronic Module
It is basically responsible for interpretingcomputing information, distribution of information, ignition system, the engine RPM limiter and the vehicle speed limiterIt reads information through many external sensors to then compute the output actions to the related systemsLimp Home Modes When low oil pressure is detected in the engine, the electronic module may automatically set default parameters to ensure the adequate operation of the ATVThe engine RPM may be limited to low RPM if some critical components failThese performance-reduced modes allow the rider to go back home which would not be possible without this advanced system
