IGNITION SYSTEM (DR-Z400)

DESCRIPTION

In the capacitor discharged ignition system, the electrical energy generated by the generator charges the
capacitor. This energy is released in a single surge at the specified ignition timing point and the current flows
through the primary side of the ignition coil. A high voltage is induced in the secondary windings of the
ignition coil, resulting in a strong spark between the spark plug gap.
