DESCRIPTION

The starter and recharging circuit consists of the battery, the starter motor and the alternator.

The battery(12V)is lead type that requires very little servicing .

IThe starter motor has a d.c. motor supplied by the battery and an energising electromagnet.

Turning the ignition key to the end position (IGN) the motor windings are powered, generating the electromagnetic forces that rotate the pinion of the motors. At the same time the electromagnet is energised that activates the pinion meshing in the flywheel crown ring, rotating the crankshaft.

The alternator recharges the battery during notmal engine rotation.

The alternator shaft (rotor) is rotated by the crankshaft by a belt. Powered by an energising current, the rotor generates a magnetic field that induces an alternating current on the fixed winding (stator.

A rectifier diode bridge on the rear of the alternator transforms the alternating current to direct current sent to recharge the battery.

A bvoltage regulator also incorporated in the alternator, keeps the voltage delivery steady (approx. 14 V) for all load variation ranges and engine speeds .

In the automatic clutch version, this system actuates a safety logic that inhibits the vehicle start up if any gear is inserted : the signal to the starter motor passes through a relay energised by the automatic clutch control unit that supplies the consent.
