Introduction - CURRENT GENERATOR

The current production system consists of the battery and the alternator.

Battery

The battery is the low maintenance, sealed lead type. The elements are sealed with pressure plugs with an anti-infiltration system and a gas evacuation device involving the actual plugs.

ALTERNATOR

The alternator should provide a sufficient current for the on-board network, at all operating speeds, for the battery to remained charged. The alternator produces an alternating current which is converted into a direct current by a special rectifier.

The alterantor shaft (rotor) is turned by the crankshaft by means of a belt. When supplied with an excitation current, the rotor sets up a magnetic field that induces an alternating current in the fixed coil (stator). A diode rectifier bridge, at the back of the alternator, transforms the alternating current into a direct current which is sent to recharge the battery. A voltage regulator maintains the current supply at a constant voltage of 14 V for all engine load and speed conditions.

A small radial fan, fixed to the pulley, cools the alternator.
