IGNITION AND STARTER SYSTEM (DR350SER)
DESCRIPTION
The capacitor discharged ignition system consists of a signal generator, COl unit. ignition coil and
spark plug. The electrical energy generated by the signal generator charges the capacitor. This energy
is released in a single surge at the specified ignition timing point. and current flows through the primary
side of the ignition coil. A high voltage current is induced in the secondary windings of the ignition
coil resulting in strong spark between the spark plug gap. Ignition cut-off circuit is incorporated in
the COl unit . If the crankshaft turns in the reverse direction and reverse current is produced . this cir-
cuit works on the capacitor to cut off the primary current of the ignition coil . It causes no sparking
between spark plug gap.
The staner system consists of a side-stand switch, neutral switch . clutch switch and side-stand re-
lay. This function is to supply the current from the battery to the side-stand relay and starter relay
only when the transmission gear is at the neutral position or when the side·stand is at the upright
position .
