Power Supply (14.00)
Alternator and Regulator System (14.02)
Description
The alternator installed to this vehicle is a Denso, SC1, 120
amp rating, with a 14.4 volt regulator.
The Alternator has an 'Altmon' signal that goes to and from
the PCM via a wire in the 3 way connector.
The ‘Altmon’ signal is monitored by the PCM which adjusts
ignition timing and fuelling if necessary to maintain idle
speed when the alternator is charging.

Relays
Another significant component in the circuits is a relay, this
is in simple terms a switch that operates on the principal of
electromagnetism. Below is the circuit symbol for a typical
relay. The relay shown below is a normally open relay in its
inoperative state i.e The arm is in the open position.
Relays can have either 4 or 5 terminals on the base. The
circuit of the relay is shown on the base or the side of the
housing. There are 2 types of numbering convention for the
relay terminals, both of which are shown below.
Below is a circuit diagram to show the function and
operation of a relay in a simple circuit.
The current from a battery for example flows through the
wires to the high power normally open switch (The arm
between pins 30 & 87A) and the low power coil (The box
between pins 85 & 86). As you can see in the example above
the lamp is in not illuminated, because the switch is open.
For the relay to operate there needs to be current flow
through the low power coil i.e Current in to the coil then
through to an earth. The current passes through the relay coil
and creates a magnetic field, this magnetic field is strong
enough to ‘grab’ the high power normally open switch.
The magnetic field pulls the switch from it’s normally open
contact to a normally closed contact. The normally closed
contact has a path to an earth, in this case it goes through a
lamp. The high power current then flows through the high power
normally open switch through the lamp and then to an earth.
This can be seen more clearly in the diagram below.Lamp
Illuminates
Busbars
A busbar is where a electrical
supply is fed into a conductive
bar, wire or pcb track and various modules or components
‘tap’ into this busbar to draw their required power. The
Central Electronic Module has 4 of these busbars internally,
each of which is supplied from an external power supply,
that supply can be a battery feed, ignition feed or a switched
supply.
The symbol shown below is the symbol used on the circuits
for a busbar, the number inside the box refers to the busbar
number in the Central Electronic Module.
Fuses
A fuse is a device used to protect a module or component
from excessive electrical current which can cause damage or
destroy that module or component. In practice the fuse is
placed in between the power source and the module or
component that is being protected.
The size or ‘Rating’ of the fuse in amps is calculated
according to the power requirements of the module or
component it is protecting with other factors being taken
into consideration. If the rating has been calculated correctly
then the fuse will ‘blow’ when excessive current passes
through it before any harm or permanent damage occurs to
the module or component it is protecting.
