216 Electrical System

NOTE: While checking the operation of the
fusible link, loosely connect the battery-
terminal only, to safeguard against damage
to the wiring harness.

(5) If the circuit is still inoperative or the fusible
link burns out again, refer the problem to an auto-
motive electrician.

RELAY LOCATIONS
The various relays employed in the vehicle elec-
trical system are located behind the fusible links
adjacent to the washer bottle in the engine compart-
ment, on the engine compartment bulkhead, under
the windscreen wiper motor and in the fuse box at the
lower right hand side of the dashboard.

The engine compartment relays power the radia-
tor fan, horn, condenser fan, bulb check, automatic
transaxle neutral safety switch, air conditioner and
condenser motor.

The fuse box relays power the fuel pump, ignition,
some accessories and the el ectronic control module.

18. TRAILER WIRING
There are several brands of trailer wiring connec-
tors available with a variet y of pin configurations. The
most common is the seven pin type which provides
for two auxiliary circuits, usually used for reverse
lamps and electric trailer brakes.

4. ENGINE BONNET
TO REMOVE, INSTAL AND ADJUST
Raise the engine bonnet and place covers on
both front mudguards. Mark the hinge mountings on
the bonnet with a soft lead pencil to aid assembly.
Place a quantity of soft rag folded several
times under each rear corner of the bonnet on the
scuttle panel. Disconnect the windscreen washer hose from
the bonnet at the tee piece. With the aid of an assistant supporting the
bonnet, remove the retaining bolts and lift the bonnet
from the vehicle. Installation is a reversal of the removal procedure
with attention to the following points:

Holding the bonnet in the position previ-
ously marked, install the bonnet hinge bolts
and
tighten to just over finger tight.
Close the bonnet and by pushing with the
hand, position the bonnet evenly in its opening.

Open the bonnet carefully and tighten the
mounting bolts. Check for correct positioning and adjust
again if necessary. Check the adjustment of the bonnet catch.
When the bonnet is closed the bonnet should align
with the front panels. When the catch is released the
bonnet should pop up sufficiently to enable the safety
catch to be released. If adjustment is necessary, mark the base
position with a pencil, loosen the retaining bolts and
move the catch in the desired direction. Tighten the
bolts and recheck.
NOTE: When adjusting the bonnet catch
ensure that the bonnet striker plate is enter-
ing centrally into the catch. Adjust the catch
or the bonnet lunges if necessary.

(7) When adjustment is complete, adjust the
bump rubbers on the radiator support panel up or
down by turning them to support the outer edges of
the bonnet.

ing bolts.

5. TAILGATE AND LOCK - HATCHBACK
TAILGATE
To Remove
Raise the tailgate and place protective covers
over the surrounding paintwork.

Using a soft lead pencil, mark around the
tailgate hinges to aid assembly. Remove the sealing grommets from the tail-
gate and disconnect the rear window washer hose. Prise out the tailgate trim panel retaining
clips and maneuver the tailgate interior trim panel
from the tailgate.
Disconnect the wiring connectors) inside the
tailgate and tie a piece of st ring to the connector(s).
