Body electrical system
1 General information
The electrical system is a 12-volt, negative
earth type. Power for the lights and all
electrical accessories is supplied by a
lead/acid-type battery which is charged by
the alternator.
This Chapter covers repair and service
procedures for the various electrical
components not associated with the engine.
Information on the battery, alternator,
distributor and starter motor will be found in
Chapter 5.
It should be noted that when portions of the
electrical system are serviced, the cable
should be disconnected from the negative
battery terminal to prevent electrical shorts
and/or fires.
2 Electrical fault finding-
general information
A typical electrical circuit consists of an
electrical component, any switches, relays,
motors, fuses, fusible links, in-line fuses or
circuit breakers related to that component
and the wiring and electrical connectors that
link the component to both the battery andthe chassis. To help you pinpoint an electrical
circuit problem, wiring diagrams are included
at the end of this Chapter.
Before tackling any troublesome electrical
circuit, first study the appropriate wiring
diagrams to get a complete understanding of
what makes up that individual circuit. Trouble
spots, for instance, can often be narrowed
down by noting if other components related to
the circuit are operating properly. If several
components or circuits fail at one time,
chances are the problem is in a fuse or earth
connection, because several circuits are often
routed through the same fuse and earth
connections.
Electrical problems usually stem from
simple causes, such as loose or corroded
connections, a blown fuse, a melted fusible
link or a bad relay. Visually inspect the
condition of all fuses, wires and connections
in a problem circuit before diagnosing it.
If testing instruments are going to be
utilised, use the diagrams to plan ahead of
time where you will make the necessary
connections in order to accurately pinpoint
the trouble spot.
The basic tools needed for electrical fault
finding include a circuit tester or voltmeter (a
12-volt bulb with a set of test leads can also
be used), a continuity tester, which includes a
bulb, battery and set of test leads, and a
jumper wire, preferably with a circuit breaker
incorporated, which can be used to bypasselectrical components. Before attempting to
locate a problem with test instruments,
use the wiring diagram(s) to decide where to
make the connections.
Voltage checks
Voltage checks should be performed if a
circuit is not functioning properly. Connect
one lead of a circuit tester to either the
negative battery terminal or a known good
earth. Connect the other lead to a electrical
connector in the circuit being tested,
preferably nearest to the battery or fuse. If the
bulb of the tester lights, voltage is present,
which means that the part of the circuit
between the electrical connector and the
battery is problem free. Continue checking the
rest of the circuit in the same fashion. When
you reach a point at which no voltage is
present, the problem lies between that point
and the last test point with voltage. Most of
the time the problem can be traced to a loose
connection. Note:Keep in mind that some
circuits receive voltage only when the ignition
key is in the Accessory or Run position.
Finding a short
One method of finding shorts in a circuit is
to remove the fuse and connect a test light or
voltmeter in its place. There should be no
voltage present in the circuit. Move the wiring
harness from side to side while watching the
test light. If the bulb goes on, there is a short Airbag system - general information . . . . . . . . . . . . . . . . . . . . . . . . . 28

to earth somewhere in that area, probably
where the insulation has rubbed through. The
same test can be performed on each
component in the circuit, even a switch.
Earth check
Perform an earth test to check whether a
component is properly earthed. Disconnect
the battery and connect one lead of a self-
powered test light, known as a continuity
tester, to a known good earth. Connect the
other lead to the wire or earth connection
being tested. If the bulb goes on, the earth is
good. If the bulb does not go on, the earth is
not good.
Continuity check
A continuity check is done to determine if
there are any breaks in a circuit - if it is
passing electricity properly. With the circuit off
(no power in the circuit), a self-powered
continuity tester can be used to check the
circuit. Connect the test leads to both ends of
the circuit (or to the “power” end and a good
earth), and if the test light comes on the circuit
is passing current properly. If the light doesn’t
come on, there is a break somewhere in the
circuit. The same procedure can be used
to test a switch, by connecting the continuity
tester to the power in and power out sides of
the switch. With the switch turned On, the test
light should come on.
Finding an open circuit
When diagnosing for possible open circuits,
it is often difficult to locate them by sight
because oxidation or terminal misalignment
are hidden by the electrical connectors.
Merely wiggling an electrical connector on a
sensor or in the wiring harness may correct
the open circuit condition. Remember this
when an open circuit is indicated when
diagnosing a circuit. Intermittent problems
may also be caused by oxidised or loose
connections.Electrical fault finding is simple if you keep
in mind that all electrical circuits are basically
electricity running from the battery, through
the wires, switches, relays, fuses and fusible
links to each electrical component (light bulb,
motor, etc.) and to earth, from which it is
passed back to the battery. Any electrical
problem is an interruption in the flow of
electricity to and from the battery.
3 Fuses- general information
The electrical circuits of the vehicle are
protected by a combination of fuses, circuit
breakers and In-line fuses. The fuse blocks
are located in the left and right side kick
panels and in the centre console glove box
(see illustrations).
Each of the fuses is designed to protect a
specific circuit, and the various circuits are
identified on the fuse panel cover.
Miniaturised fuses are employed in the fuse
blocks. These compact fuses, with blade
terminal design, allow fingertip removal and
renewal. If an electrical component fails,
always check the fuse first. The best way tocheck the fuses is with a test light. Check for
power at the exposed terminal tips of each
fuse. If power is present on one side of the
fuse but not the other, the fuse is blown. A
blown fuse can be confirmed by visual
inspection (see illustration).
Be sure to renew blown fuses with the
correct type. Fuses of different ratings are
physically interchangeable, but only fuses of
the proper rating should be used. Replacing a
fuse with one of a higher or lower value than
specified is not recommended. Each electrical
circuit needs a specific amount of protection.
The amperage value of each fuse is moulded
into the fuse body.
If the renewal fuse immediately fails, don’t
renew it again until the cause of the problem
is isolated and corrected. In most cases, this
will be a short circuit in the wiring caused by a
broken or deteriorated wire.
4 In-line fuses-
general information
Some circuits are protected by in-line
fuses. In-line fuses are used in such circuits
as the windscreen wiper system, headlight
12•2 Body electrical system
3261 Jaguar XJ6 3.1a The left side fusebox is located in the passenger’s side kick
panel, behind the fuse panel cover
3.1b The right side fusebox is located in the driver’s side kick
panel, behind the fuse panel cover
3.1c A third fusebox is located in the
centre console glove box3.3 When a fuse blows, the metal element
between the terminals melts - the fuse on
the left is blown, the one on the right is ok

wash system, radio memory and the ABS
main feed and pump circuits.
In-line fuses are located through out the
vehicle depending on the year, make and
model. Consult the wiring diagrams at the end
of this Chapter for further information.
In-line fuses also have a blade terminal
design, which allow fingertip removal and
renewal. If an electrical component fails,
always check the fuse first. A blown fuse is
easily identified through the clear plastic
body. Inspect the element for evidence of
damage (see illustration 3.3).
Be sure to renew blown fuses with the
correct type. Fuses are usually colour-coded
to indicate their rating. Fuses of different
ratings are physically interchangeable, but
only fuses of the proper rating should be
used. Replacing a fuse with one of a different
value than specified is not recommended.
Each electrical circuit needs a specific
amount of protection. The amperage value of
each fuse is moulded into the fuse body.If the renewal fuse immediately fails, don’t
renew it again until the cause of the problem
is isolated and corrected. Don’t substitute
anything else for the fuse. In most cases, this
will be a short circuit in the wiring caused by a
broken or deteriorated wire.
5 Circuit breakers-
general information
Circuit breakers generally protect
components such as electric windows, central
locking and headlights. On some models the
circuit breaker resets itself automatically, so
an electrical overload in the circuit will cause it
to fail momentarily, then come back on. If the
circuit doesn’t come back on, check it
immediately. Once the condition is corrected,
the circuit breaker will resume its normal
function. Some circuit breakers have a button
on top and must be reset manually.To test a circuit breaker, use an ohmmeter
to check continuity between the terminals. A
reading of zero to 1.0 ohms indicates a good
circuit breaker. An open circuit reading on the
meter indicates a bad circuit breaker.
6 Relays- general information
and testing
2
General information
Several electrical accessories in the vehicle,
such as the fuel injection system, electric
windows, central locking, etc, use relays to
transmit the electrical signal to the component.
Relays use a low-current circuit (the control
circuit) to open and close a high-current circuit
(the power circuit). If the relay is defective, that
component will not operate properly. The
relays are mounted throughout the vehicle (see
illustrations). If a faulty relay is suspected, it
