Starter motor brushes
(later models) - renewal#
25When renewing the starter motor brushes
on later models, the old brushes will need to
be crushed (in a vice or with a hammer) and
their leads then soldered to the new brushes.
Fuses - later models
26The fuse arrangement is slightly different
on later models, but the circuits protected are
still identified by a symbol. Refer to the
Specifications Section for full details. Note
also the terminal block with plastic cover,
which can be used to isolate the battery from
the electrical system by disconnecting the
leads from the terminals (photos).
Relays (Turbo ie models) -
general
27On Turbo ie models, the relays mounted
in the fuse block are as shown in Fig. 13.103.
Additional relays are located as follows:
Headlamp relay - on lead under main fuse
blockFuel injection system main control relay -
adjacent to airflow meter
Headlamps later models
28The headlamp units fitted on later models
differ according to model, but the bulb and
unit replacement details are generally the
same as described for previous models in
Chapter 9. Note that the rubber cover can
only be fitted with the tab to the top as shown
(photo).
Headlamp beam adjusters for
load compensation - later
models
29Some later models are fitted with
headlamp beam adjusters which allowtemporary resetting to be made (such as
when the car is fully loaded). Access to these
adjusters is made by lifting the bonnet (photo).
30Turn the adjusters anti-clockwise to lower
the beam to the normal level or clockwise to
raise the beam (when the car is unloaded).
Repeat the procedure on the opposite
headlamp unit an equal amount.
31Other later models have separate
horizontal and vertical beam adjusters,
positioned as shown (photos). A load
compensating lever is attached to the
adjusters to enable temporary resetting of the
headlamp beams, without changing the
normal adjustment. Turn the lever to the
appropriate side (right or left) to make the
adjustment as required. The normal setting

adjustment procedures are the same as those
outlined for the previous model units in
Chapter 9, but ensure that the load
compensation lever is turned to the “O”
(normal load setting) position before making
any adjustments.
Headlamp unit removal - later
models
32The removal and refitting procedures
described in Chapter 9 also apply to the later
headlamp type, but note that later units are
secured in position by three retaining screws.
Headlamp dim-dip system -
description
33On later models, the wiring circuit has
been modified to prevent the car being drivenon parking lamps only in built-up areas.
34Headlamp intensity is reduced by the
transformer located at the front of the engine
compartment (photo).
35Any attempt to start the car with parking
lamps only on will automatically cause the
headlamps to switch on with a low-intensity
dipped beam. Dipped and main beam
function normally.
36The headlamp dim-dip system is a legal
requirement for all UK models registered after
April 1st, 1987.
Front fog lamps - bulb/unit
removal and refitting
and beam adjustment
ª
37Ensure that the front fog lamps are
switched off, then unscrew the two retainingscrews and withdraw the lamp unit from the
underside of the front bumper (photos).
38Undo the retaining screw and remove the
access cover from the unit (photo).
39Disconnect the wiring connector from the
bulb, release the clips and withdraw the bulb
from the lamp (photo).
40Refit in the reverse order of removal.
Check the light for satisfactory operation and
if the beam requires resetting, turn the
adjustment screw in the required direction.
41To adjust the beam, position the car 5 m
from, and square on to, a wall or similar.
42Measure the height of the centre of the
lamp lens from the ground and mark the
position on the wall. Switch on the lamp. The
demarcation line (cut-off) of the light should
be below the mark on the wall by 50 mm plus
one-third of the ground-to-lamp centre
measurement. Adjust the beam as required
using the long centre screw.
Horn - relocation
43The single horn, on applicable models, is
now located behind the grille, bolted on a
bracket attached to the top rail (photo).
