GENERAL
The ignition system consist of different sub-systems
where some are interrelated.
Unregulated AC current is produced by the mag-
neto. Part of the AC current is rectified and regu-
lated for the charging system.
A 12 volts battery supplies the Multi-Purpose Elec-
tronic Module (MPEM) with DC current.
Refer to CHARGING SYSTEM.
The following type of ignition system is used:
– Direct Current-Digital Capacitor Discharge Igni-
tion (DC-CDI).
Magneto System
The magneto is the primary source of electrical
energy. It transforms magnetic field into electric
current (AC).
Trigger Coil
The trigger coil is mounted outside the rotor (in-
side the magneto housing of the engine) and is not
adjustable.
1. Trigger coil
Its purpose is to signal the piston position to the
Multi-Purpose Electronic Module. The rotor has
four protrusions (90 degrees apart) that, when cou-
pled with the trigger coil, accomplish the signaling.
