DESCRIPTION OF ALTERNATOR CHARGING SYSTEM
2
The charging system is essentially comprised of
an alternator and a charge regulator (see Fig. 1).
Alternator
The alternator is, fundamentally, an A.C.
generator.
Its main components are:
The rotor, or wound field magnet, which runs on
2 bearings and is fed by two brushes rubbing
against tillo polished slip rings.
The field current admitted in the rotor winding
is limited by the regulator.
The stator, or armature, which is comprised of
two windings.

The housing, which carries the following terminals:
• BAT or

terminal.
• AUXILIARY terminal to connect th£ charging
indicator lamp.
• EARTHING tenni nal.
FIELD CURRENT.
In operation, two diodes included in the stator
circuit, between earth and the annature winding
output, rectify the alternating current produced by
the alternator.
Another diode, known as the insulating diode, allows
a charging indicator lamp to be fitted, whilst
preventing the battery from discharging through this
lamp and preventing the field magnets from remaining
permanently live when switched off.
