2Flatten the lockwasher which secures the
guide plate centre bolt. Remove the centre
bolt and the two bolts which hold the guide
plate to the floor; remove the guide plate.
3Wedge a piece of wood between the
crossmember and the floor.
4Draw the insulator out with the special tool
(see illustration).
5Smear the new insulator with glycerine or
liquid soap, then press it in as follows.
6Use the special tool spindle or other long
M12 bolt. Screw a nut up to the bolt head,
then fit a plain washer and the insulator onto
the bolt. Pass the bolt through the hole in the
crossmember and screw it into the floor, then
press the insulator home by winding the nut
and washer up the bolt.
7Remove the installation tool and the wood.
8Refit the guide plate, tightening the bolts to
the specified torque. Secure the centre bolt
with the lockwasher.
9Lower the vehicle.
1Remove the rear hub.
2Disconnect both rear brake flexible hoses
from the brake pipes. Free the brake pipes
from the brackets on the lower arms.
3Unclip the handbrake cable from the lower
arm.
4Remove the rear spring.
5Remove the lower arm-to-crossmember
bolts. Withdraw the lower arm.6Renew the rubber bushes if wished, using
lengths of tube or sockets and a vice, or large
nuts and bolts. Lubricate the new bushes with
glycerine or liquid soap.
7Refit by reversing the removal operations,
tightening the lower arm-to-crossmember
bolts with the weight of the vehicle back on its
wheels. Bleed the brake hydraulic system on
completion.
1Raise and support the rear of the vehicle.
2Separate the anti-roll bar from the link rods
on each side by prising them free (see
illustration).
3Unbolt the two anti-roll bar brackets.
Remove the bar, brackets and bushes (see
illustration).
4Refit by reversing the removal operations.
Tighten the bracket bolts to the specified
torque.
1Working inside the vehicle, remove the
luggage area side trim to gain access to the
shock absorber top mounting.
2Raise and support the rear of the vehicle.
Raise a jack under the rear suspension lower
arm to take the load off the shock absorber.3On models with ride height control,
disconnect the air line from the shock
absorber.
4Unbolt the shock absorber top mounting
(see illustration).
5Unbolt the shock absorber lower mounting
(see illustration). Pull the shock absorber out
of the lower mounting bracket and remove it.
6Refit by reversing the removal operations.
Tighten the shock absorber mountings to the
specified torque. On models with ride height
control, use new O-rings on the air line union.
The ride height control system is an optional
extra, designed to keep the rear suspension
height constant regardless of vehicle load.
This is obviously useful if heavy loads are often
carried, or if the vehicle is used for towing.
The main components of the system are a
height sensor, a compressor and two special
rear shock absorbers. The compressor
supplies air to the shock absorbers, so
“pumping up” the rear suspension, when so
commanded by the height sensor. Other
components include the connecting pipes,
electrical wiring and a compressor relay. The
relay is mounted behind the glovebox.
Variations in vehicle height are not
recognised by the system for approximately
20 seconds, in order to prevent responses to
temporary changes such as those induced by

The electrical system is a 12 volt, negative
earth type. Electricity is generated by an
alternator, belt-driven from the crankshaft pulley.
A lead-acid battery provides a reserve of power
for starting and when the demands of the system
temporarily exceed the alternator output.
The battery negative terminal is connected
to “earth” - vehicle metal - and most electrical
system components are wired so that they
only receive a positive feed, the current
returning via vehicle metal. This means that
the component mounting forms part of the
circuit. Loose or corroded mountings can
therefore cause apparent electrical faults.
Many semiconductor devices are used in
the electrical system, both in the “black
boxes” which control vehicle functions and in
other components. Semiconductors are very
sensitive to excessive (or wrong polarity)
voltage, and to extremes of heat. Observe the
appropriate precautions to avoid damage.
Although some repair procedures are given
in this Chapter, sometimes renewal of a well-
used item will prove more satisfactory. The
reader whose interests extend beyond
component renewal should obtain a copy of
the “Automobile Electrical Manual”, available
from the publishers of this book.
Before starting work on the electrical
system, read the precautions listed in “Safety
first!” at the beginning of the manual.
Note:Refer to the precautions given in “Safety
first!” and in Section 1 of this Chapter before
starting work. The following tests relate to testing
of the main electrical circuits, and should not be
used to test delicate electronic circuits (such as
anti-lock braking systems), particularly where an
electronic control unit (ECU) is involved.
General
1A typical electrical circuit consists of an
electrical component, any switches, relays,
motors, fuses, fusible links or circuit breakers
related to that component, and the wiring and
connectors which link the component to both
the battery and the chassis. To help to
pinpoint a problem in an electrical circuit,
wiring diagrams are included at the end of this
Chapter.
2Before attempting to diagnose an electrical
fault, first study the appropriate wiring
diagram, to obtain a more complete
understanding of the components included in
the particular circuit concerned. The possible
sources of a fault can be narrowed down by
noting whether other components related to
the circuit are operating properly. If several
components or circuits fail at one time, the
problem is likely to be related to a shared fuse
or earth connection.
3Electrical problems usually stem from
simple causes, such as loose or corroded
connections, a faulty earth connection, a
blown fuse, a melted fusible link, or a faulty
relay. Visually inspect the condition of all
fuses, wires and connections in a problem
circuit before testing the components. Use the
wiring diagrams to determine which terminal
connections will need to be checked in order
to pinpoint the trouble-spot.
4The basic tools required for electrical fault-
finding include: a circuit tester or voltmeter (a
12-volt bulb with a set of test leads can also
be used for certain tests), a self-powered test
light (sometimes known as a continuity tester),
an ohmmeter (to measure resistance), a
battery and set of test leads, and a jumper
wire, preferably with a circuit breaker or fuse
incorporated, which can be used to bypass
suspect wires or electrical components.
Before attempting to locate a problem with
test instruments, use the wiring diagram to
determine where to make the connections.
5To find the source of an intermittent wiring
fault (usually due to a poor or dirty connection,
or damaged wiring insulation), an integrity testcan be performed on the wiring, which
involves moving the wiring by hand, to see if
the fault occurs as the wiring is moved. It
should be possible to narrow down the source
of the fault to a particular section of wiring.
This method of testing can be used in
conjunction with any of the tests described in
the following sub-Sections.
6Apart from problems due to poor
connections, two basic types of fault can
occur in an electrical circuit - open-circuit or
short-circuit.
7Open-circuit faults are caused by a break
somewhere in the circuit, which prevents
current from flowing. An open-circuit fault will
prevent a component from working, but will
not cause the relevant circuit fuse to blow.
8Short-circuit faults are caused by a “short”
somewhere in the circuit, which allows the
current flowing in the circuit to “escape” along
an alternative route, usually to earth. Short-
circuit faults are normally caused by a
breakdown in wiring insulation, which allows a
feed wire to touch either another wire, or an
earthed component such as the bodyshell. A
short-circuit fault will normally cause the
relevant circuit fuse to blow. Note: A short-
circuit that occurs in the wiring between a
circuit’s battery supply and its fuse will not
cause the fuse in that particular circuit to blow.
This part of the circuit is unprotected - bear
this in mind when fault-finding on the vehicle’s
electrical system.
Finding an open-circuit
9To check for an open-circuit, connect one
lead of a circuit tester or voltmeter to either the
negative battery terminal or a known good earth.
10Connect the other lead to a connector in
the circuit being tested, preferably nearest to
the battery or fuse.
11Switch on the circuit, bearing in mind that
some circuits are live only when the ignition
switch is moved to a particular position.
12If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading,
as applicable), this means that the section of

61Refer to Chapter 7 part B.
Fuses
1The battery positive (live) lead is protected
by a fusible link. If this link melts, a major
short-circuit is indicated and expert advice
should be sought before repairing it.
2The main fuse/relay box is located under the
bonnet, near the bulkhead on the right-hand
side. It contains up to 24 fuses and nearly as
many relays (according to equipment). Fuse
applications are listed on the underside of the
fuse box lid (see illustration).
3There is an auxiliary fuse box inside the
vehicle, accessible after opening the glovebox
(see illustration). An in-line fuse for the radio
is located under the facia on the left-hand
side, near the heater.4The“blade” type fuses are colour-coded to
show their current rating. A blown fuse can be
recognised by the melted wire link in the
middle.
5To renew a blown fuse, first switch off the
circuit concerned. Pull the old fuse out of its
holder, using tweezers or long-nosed pliers.
Press in a new fuse of the same rating and try
the circuit again.
6If the new fuse blows immediately or within
a short time, do not carry on renewing fuses
but look for a short-circuit in the wiring to the
item(s) protected by the fuse. When more than
one item is protected by a single fuse,
switching on one item at a time until the fuse
blows will help to isolate the defect.
7Never fit a fuse of a higher rating (current
capacity) than specified, and do not bypass
fuses with silver foil or strands of wire. Serious
damage, including fire, could result.
8In some positions (such as for power
window and seat adjustment motors) circuit
breakers are fitted instead of fuses. These are
normally self-resetting once the cause of the
overload has been cleared.
Relays
9If a circuit or system served by a relay
develops a fault, always remember that the
problem could be in the relay. Testing is by
substitution of a known good unit. Beware of
substituting relays which look the same but
perform different functions(see illustration).10To renew a relay, simply unplug it from its
holder and plug in the new one. Access to the
relays in the main fuse box is as described for
the fuses. Access to the relays located behind
the facia is achieved by removing the facia
top.
11The sliding roof relay is located in the
overhead console.
Control units and modules
12The two major modules are the EEC IV
module (on fuel-injection models) and the ABS
control module. These are located below the
glovebox on the passenger side, and are
accessible after removing the under-dash trim.
13As with relays, testing by the home
mechanic is limited to substitution of known
good units. This is likely to be prohibitively
expensive on a trial and error basis so in case
of problems a Ford dealer or other competent
specialist should be consulted at an early
stage.
1Disconnect the battery negative lead and
unlock all the doors before starting work on
the central locking system. Make sure that the
keys are outside the vehicle before
reconnecting the battery on completion.
2Remove the door interior trim panel.

1Remove the overhead console.
2Remove the three bolts which secure the
motor (see illustration).Lower the motor,
disconnect the multi-plug and remove it.
Recover the relay.
3When refitting, make sure that the motor
drivegear meshes with the roof operating
mechanism. Refit the relay, reconnect the
multi-plug and secure the motor with the three
bolts.
4Check the operation of the motor, then refit
the overhead console.1All vehicles are fitted with an electrical
speedometer sender unit instead of a
mechanical cable. The sender unit is located on
the left-hand side of the transmission extension.
2Raise and securely support the front of the
vehicle. Place a drain pan underneath the
speedometer sender unit.
3Remove the securing bolt, pull the sender
unit out of the transmission and disconnect
the multi-plug (see illustration). Be prepared
for some spillage of gearbox oil or ATF
(automatic transmission fluid).
4If a new sender unit is being fitted, transfer
the driven gear and circlip from the old unit.
On automatic transmission models, also
transfer the O-ring.
5If the old sender unit had two connecting
wires and the new unit has three, the brown
wire must be cut at the multi-plug and an earth
tag fitted (see illustration).Consult a Ford
dealer if in doubt.
6Fit the new sender unit, using a new bolt
(M6 x 25 mm for manual gearbox, M6 x 35 mm
for automatic transmission). Besides the
sender unit, the bolt also secures the new
earth tag (when applicable), the radio earth
strap and the multi-plug retaining bracket.
7Connect the multi-plug and fit it to the
bracket.8If any spillage of gearbox oil or transmission
fluid occurred, top-up the level before the
vehicle is next run.

The alarm system is available as an optional
extra. On vehicles so equipped, the alarm is
automatically set by locking the driver’s or
front passenger’s door with the key. After a
brief delay (approximately 20 seconds), the
alarm will be set off if the doors, bonnet or
tailgate are opened.
The only way to disarm the alarm system is
by unlocking one of the front doors with the
key. Even if the key is used to open the
tailgate, if the alarm is set it will go off.
