1988 OPEL CALIBRA fuse box

to-metal contact between components, due
to flexible rubber mountings, etc.
To 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.
If 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 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 by applying a coat of petroleum jelly or
silicone-based grease.
3Fuses and relays - general
Fuses
1Fuses are designed to break a circuit when
a predetermined current is reached, to protect
the components and wiring which could be
damaged by excessive current flow. Any
excessive current flow will be due to a fault in
the circuit, usually a short-circuit (Section 2).
2The main fuses and relays are located in a
panel at the lower right-hand side of the facia,
under a hinged cover (see illustration).
3The circuits protected by the various fuses
and relays are marked on the inside of the
panel cover.
4A blown fuse can be recognised from its
melted or broken wire.
5To remove a fuse, first ensure that the
relevant circuit is switched off. Then open the
cover and pull the relevant fuse or relay from the
panel (see illustration). If desired, the lower
end of the panel can be tilted forwards, after
releasing the retaining clips to improve access. 6Before renewing a blown fuse, trace and
rectify the cause, and always use a fuse of the
correct rating. Never substitute a fuse of a
higher rating, or make temporary repairs using
wire or metal foil, as more serious damage or
even fire could result.
7Spare fuses are provided in the blank
terminal positions in the fusebox.
8Note that the fuses are colour-coded, see
Specifications. Refer to the wiring diagrams
for details of the fuse ratings and the circuits
protected.
Relays
9A relay is an electrically operated switch,
which is used for the following reasons:
a)A relay can switch a heavy current
remotely from the circuit in which the
current is flowing, allowing the use of
lighter-gauge wiring and switch contacts.
b)A relay can receive more than one control
input, unlike a mechanical switch.
c)A relay can have a timer function - for
example, the intermittent wiper relay.
10Most of the relays are located at the rear
of the main fusebox (remove the securing
screws and pull the fusebox forwards to
improve access). The rear wiper motor relay is
located in the tailgate, behind the tailgate trim
panel. On some models, additional engine-
related relays are located in the relay box
mounted on the left-hand side of the engine
compartment.
11On certain models, additional relays are
located in a box at the left-hand rear of the
engine compartment (see illustration).
12If a circuit or system controlled by a relay
develops a fault, and the relay is suspect,
operate the system. If the relay is functioning, it
should be possible to hear it “click” as it is
energised. If this is the case, the fault lies with
the components or wiring of the system. If the
relay is not being energised, then either the
relay is not receiving a main supply or a
switching voltage, or the relay itself is faulty.
Testing is by the substitution of a known good
unit, but be careful - while some relays are
identical in appearance and in operation, others
look similar but perform different functions.
13To remove a relay, first ensure that the
relevant circuit is switched off. The relay can
then simply be pulled out from the socket,
and pushed back into position.

1Correct alignment of the headlamp beams
is most important, not only to ensure good
vision for the driver, but also to protect other
drivers from being dazzled.
2Accurate alignment should be carried out
using optical beam setting equipment.
3In an emergency, adjustments may be
made by turning the adjustment screws
shown (see illustrations). If an adjustment is
made, the alignment should be checked using
beam setting equipment at the earliest
opportunity.
4All 1992-on models are fitted with the
headlamp aim adjustment system, operated
through the facia-mounted switch (see
illustration).
a)Position ‘0’, is for correct alignment if just
the driving seat is occupied.
b)Position ‘1’, if all seats are occupied.
c)Position ‘2’, if all seats occupied and
luggage.
d)Position ‘3’, for just driver and luggage.
28Headlamp dim-dip system -
general, removal and refitting
3
General
1The system (where fitted) is governed by the
dim-dip control unit mounted either behind
and above the glovebox (early models), or
behind the main fuse panel (later models).
2The control unit uses the oil pressure
warning lamp circuit to ensure that, when theengine is running and the sidelamps are
switched on, reduced current is fed to the
headlamp dipped-beam circuits. This lights
the headlamps with approximately one-sixth
of their normal power so that the vehicle
cannot be driven using sidelamps alone.
3To locate the dim-dip control unit, open the
main fuse panel covering flap and unclip it
from its bottom and top mountings (Section 3).
Then use a torch to see whether the unit is
fastened to the plastic bracket behind the facia
and fuse panel. The unit is usually rectangular,
of black plastic, and can be identified by the
colours of the five wires leading to it (see
applicable wiring diagram).
Removal
4If the unit can be seen, remove the driver’s
side lower facia and footwell trim panels
(Chapter 11), then unscrew the four retaining
screws and lower the plastic bracket until the
control unit can be detached.
5If the unit cannot be seen, remove the
glovebox assembly (Chapter 11). The unit will
be fastened to the underside of the facia top
surface.

62Wiring diagrams -general
1The wiring diagrams are of the current flow
type, each circuit being shown in the simplest
possible fashion. Note that since the diagrams
were originally written in German (to the DIN
standard), all wire colours and abbreviations
used on the diagrams themselves are in
German. Refer to the information given
overleaf for clarification.
2The bottom line of the diagram represents
the “earth” or negative connection; the
numbers below this line are track numbers,
enabling circuits and components to be
located using the key.
3The lines at the top of the diagram
represent “live feed” or positive connection
points. The line marked “30” is live at all
times, that marked “15” is live only when the
ignition is switched on.
4Numbers on the diagram that are framed in
square boxes at the end of a wire show the
track reference number in which that wire is
continued. At the point indicated will be
another framed number referring back to the
circuit just left.
5As an example of how to use the diagrams,
trace with the help of the following text the
reversing lamp switch circuit located between
track reference numbers 496 and 498 on the
1991 model year diagram on page 12•40.
6Starting at the top of track 497, the supply
for the circuit comes from the line “15”,
showing that the circuit is fed only when the
ignition is switched on, through fuse 22 (F22,rated at 10 amps). Note that this fuse can also
protect the feed for several other circuits,
some of which may not be applicable to the
vehicle being worked on.
7If the vehicle in question has a manual
transmission (MT), the circuit continues along
a black wire of 0.75 mm cross-section (as
shown by “SW 0.75” in the wire path), through
terminal 12 of connector X5 to the reversing
lamp switch S7. From the switch the circuit
continues along a white wire, with a black
tracer and of 0.75 mm cross-section (WSSW
0.75), through terminal 2 of connector X5 and
terminal 1 of connector X6, to the reversing
lamp bulbs (E17 and E18). The circuit is
completed by a brown wire from each
bulbholder to earth; in this case the “earth”
wire simply attaches the component to the
nearest piece of metal bodywork, but in other
cases earthing is achieved by the component
mounting and no wire is needed. The diagram
shows, as simply as possible, that when the
switch contacts (which are normally open) are
closed by the driver selecting reverse gear,
current is allowed to flow to earth through the
switch and bulbs causing the reversing lamps
to light.
8If the vehicle in question has automatic
transmission (AT), the circuit differs in that the
“live feed” goes from fuse 22 to terminal “F” of
the transmission selector lever position switch
connector X46 (track reference number 773).
When position “R” is selected, terminals “F”
and “G” are connected so that the circuit feed
continues (back to track reference number
496, the “RFS/reversing lamp” circuit) along
the same route described above for manual
transmission models.
