ELECTRICAL EQUIPMENT
DESCRIPTION
Do not disconnect battery cables while the engine is
running or damage to the semi-conductor devices
may occur. It is also inadvisable to break or make any
connections in the charging and control circuits while
the engine is running.
The electrical system is Negative ground, and it is
most important to ensure correct polarity of the
electrical connections at all times. Any incorrect
connections made when reconnecting cables may
cause irreparable damage to the semi-conductor
devices used in the A.C. generator and regulator.
Incorrect polarity would also seriously damage any
transistorized equipment such as the radio.
The electronic voltage regulator employs micro-circuit
techniques resulting in improved performance under
difficult service conditions. The whole assembly is
encapsulated in silicone rubber and housed in an
aluminium heat sink, ensuring complete protection
against the adverse effects of temperature, dust, and
moisture etc.
WARNING: During battery removal or
before carrying out any repairs or
maintenance to electrical components
always disconnect the battery negative lead first.
If the positive lead is disconnected with the
negative lead in place, accidental contact of tools
to any earthed metal part could cause a severe
spark, possibly resulting in personal injury. Upon
installation of the battery the positive lead should
be connected first.
The regulating voltage is set during manufacture to
give the required regulating voltage range of 14.2 ±
0.2 volts, and no adjustment is necessary. The only
maintenance needed is the occasional check on
terminal connections and wiping with a clean dry
cloth.
The system provides for direct connection of a charge
(ignition) indicator warning light, and eliminates the
need for a field switching relay or warning light control
unit. As the warning lamp is connected in the charging
circuit, lamp failure will cause loss of charge. Lamp
should be checked regularly and spare carried.
A.C. GENERATOR - A127/100
When using rapid charge equipment to re-charge the
battery, the battery must be disconnected from the
vehicle.
The A.C. generator is a three phase, field sensed unit.
The rotor and stator windings produce three phase
alternating current, AC, which is rectified to direct
current, DC. The electronic voltage regulator unit
controls the A.C. generator output voltage by high
frequency switching of the rotor field circuit.
NOTE: For description and operation of
electrical circuits see separate
publication:- Electrical Troubleshooting
Manual.
It is essential that good electrical connections are
maintained at all times. Of particular importance are
those in the charging circuit (including those at the
battery) which should be occasionally inspected to
see that they are clean and tight. In this way any
significant increase in circuit resistance can be
prevented.
