the circuit between the relevant connector and
the battery is problem-free.
13Continue to check the remainder of the
circuit in the same fashion.
14When a point is reached at which no
voltage is present, the problem must lie
between that point and the previous test point
with voltage. Most problems can be traced to
a broken, corroded or loose connection.
Finding a short-circuit
15To check for a short-circuit, first disconnect
the load(s) from the circuit (loads are the
components which draw current from a circuit,
such as bulbs, motors, heating elements, etc).
16Remove the relevant fuse from the circuit,
and connect a circuit tester or voltmeter to the
fuse connections.
17Switch on the circuit, bearing in mind that
some circuits are live only when the ignition
switch is moved to a particular position.
18If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading),
this means that there is a short-circuit.
19If no voltage is present, but the fuse still
blows with the load(s) connected, this
indicates an internal fault in the load(s).
Finding an earth fault
20The battery negative terminal is connected
to “earth” - the metal of the engine/transmission
and the car body - and most systems are wired
so that they only receive a positive feed, the
current returning via the metal of the car body.
This means that the component mounting andthe body form part of that circuit. Loose or
corroded mountings can therefore cause a range
of electrical faults, ranging from total failure of a
circuit, to a puzzling partial fault. In particular,
lights may shine dimly (especially when another
circuit sharing the same earth is in operation),
motors (eg wiper motors or the radiator cooling
fan motor) may run slowly, and the operation of
one circuit may have an apparently-unrelated
effect on another. Note that on many vehicles,
earth straps are used between certain
components, such as the engine/transmission
and the body, usually where there is no metal-to-
metal contact between components, due to
flexible rubber mountings, etc.
21To check whether a component is properly
earthed, disconnect the battery, and connect
one lead of an ohmmeter to a known good
earth point. Connect the other lead to the wire
or earth connection being tested. The
resistance reading should be zero; if not,
check the connection as follows.
22If an earth connection is thought to be
faulty, dismantle the connection, and clean
back to bare metal both the bodyshell and the
wire terminal, or the component’s earth
connection mating surface. Be careful to
remove all traces of dirt and corrosion, then
use a knife to trim away any paint, so that a
clean metal-to-metal joint is made. On
reassembly, tighten the joint fasteners
securely; if a wire terminal is being refitted, use
serrated washers between the terminal and
the bodyshell, to ensure a clean and secure
connection. When the connection is remade,
prevent the onset of corrosion in the future byapplying a coat of petroleum jelly or silicone-
based grease, or by spraying on (at regular
intervals) a proprietary ignition sealer, or a
water-dispersant lubricant.
Headlight
1Open and prop the bonnet. Remove the
cover from the rear of the headlight unit by
twisting it anti-clockwise.
2Disconnect the wiring plug from the
headlight bulb. Release the spring clip by
squeezing its legs together and move it clear
of the bulb (see illustration).
3Remove the headlight bulb (see
illustration). Caution: If the lights have just
been in use, the bulb may be extremely hot.
4When handling the new bulb, use a tissue or
clean cloth to avoid touching the glass with
the fingers. If the glass is accidentally touched,
wipe it clean using methylated spirit. Moisture
and grease from the skin can cause
blackening and rapid failure of the new bulb.
5Fit the new bulb, making sure that the legs
and cut-outs in the bulb base and the reflector
match up. Secure with the spring clip.
6Reconnect the wiring plug. Check the
headlight for correct operation, then refit and

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.

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.

1The rear headphone relay is located behind
the facia, next to the AWS control assembly
and the speed control module (when fitted). Its
function is to mute the loudspeakers when the
headphones are plugged into the rear
entertainment console.
2To remove the relay, first remove the AWS
control assembly and (if applicable) the speed
control unit.
3Disconnect the relay multi-plug, undo its

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.

The components of the alarm system are a
control module, tripping switches, activating
switches, an alarm horn and a signal buzzer.
The control module is located behind the
facia. It determines whether the alarm is set or
not, monitors the tripping switches and the
ignition circuit, and limits the duration of the
alarm to 30 seconds. This last item is a legal
requirement. The control module also
operates the signal buzzer to tell the driver
that the alarm is set, and controls the activator
delay.
The tripping switches on the doors and
tailgate are the same as those used for “open
door” warnings in the AWS. The bonnet switch
is peculiar to the alarm system.
The activating switches are fitted to the
front door lock barrels, where they are
activated by a lug on the end of the barrel.
They only make contact momentarily as the
lock is operated.
The alarm horn is mounted next to the
battery. Both the horn and its leads are
claimed to be inaccessible without opening
the bonnet. The signal buzzer is also mounted
under the bonnet.
No service, repair or component renewal
procedures have been published for the alarmsystem components on earlier models. Any
problems arising which cannot be dealt with
by component substitution should therefore
be referred to a Ford dealer.
