lock FORD GRANADA 1985 Service Repair Manual

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.

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.
