17. FUSES, FUSIBLE LINKS AND RELAYS

TO CHECK AND RENEW FUSE
NOTE: If a fuse is found to be faulty or
burnt out, use a replacement fuse of the
specified amperage only. The specified amp-
erage is marked on the fuse.

The use of a higher amperage fuse than
that specified could cause damage to the
vehicle wiring harness.

The fuses are mounted in a fuse box
located in the lower right hand corner of the
dashboard.

Remove the cover from the lower right hand
corner of the dashboard and using the information
marked on the fuse box, locate the fuse protecting the
circuit at fault. Pull the fuse out of the fuse box and inspect
it for serviceability.
Should the fuse appear to be in a serviceable
condition, test its continuity with an ohmmeter or test
lamp. Should the fuse be faulty or burnt out,
install
a new fuse of the same amperage. If the circuit is still inoperative or the fuse
burns out again, test the circuit as previously de-
scribed in this section or refer the problem to an
automotive electrician.
TO CHECK AND RENEW FUSIBLE LINK

NOTE: If a fusible link is found to be faulty
or burnt out, use a genuine replacement
fusible link of the specified amperage only.

The use of a higher amperage fusible link
than that specified could cause damage to
the vehicle wiring harness.

A new fusible link should never be in-
stalled until the fault which caused the
original link to fail has been repaired.

The fusible links installed to protect the
vehicles wiring system are located adjacent
to the washer bottle on the right hand inner
mudguard.

Disconnect the negative battery terminal
Check the fusible link visually for service-
ability.
Should the fusible link appear to be in a
serviceable condition, test its continuity using
an
ohmmeter or a test lamp. If the fusible link proves to be faulty, install
a
new fusible link and have an assistant temporarily
connect the battery while the circuit is checked for
operation.

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.

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.

Electrical System 217
When installing a trailer socket, it may be neces-
sary to replace the original vehicle flasher unit with a
heavy duty unit to maintain the flash rate in accor-
dance with local regulations. Local regulations may
also require the installation of a dashboard mounted
repeater lamp.

Should the trailer socket and plug not be matched,
adaptors can be made or obtained to facilitate con-
nection.

TO INSTAL TRAILER SOCKET.
The minimum materials required are a trailer
socket, mounting bracket, seven core flex, insulated
wiring connectors and a rubber grommet.

(1) Disconnect the negative battery terminal.

(5) Drill a suitably si
zed hole through the vehicle
floor and install a rubber grommet to the hole.

NOTE: Before drilling the hole, check
whether there is an existing hole which may-
be used. Ensure that a rubber grommet is
installed to prevent chafing of the wires.

Pass the seven core flex through the rubber
grommet. Cut the seven core flex to the required length
and slide the dust cover onto the flex. Remove approximately 15 mm of insulation
from each wire in the flex.
Connect the wires of the seven core flex to
the terminals of the socket, using the standard wiring
code and following the socket manufacturers connec-
tion procedure. Assemble the socket and install the dust cover
to the rear of the socket. Install the mounting bracket as close as
possible to the tow bar ball and high enough to
maintain vehicle ground clearance. Install the socket to the mounting bracket.
Connect a trailer plug to the socket and test
for correct lamp operation.
TO INSTAL TRAILER PLUG

The minimum materials required are a trailer
plug, seven core flex and insulated wiring connectors.

The installation procedure for the trailer plug is
similar to that for the socket with attention to the
following points:

Connect the trailer wiring to the plug accord-
ing to the standard wiring color code and the plug
manufacturers instructions. Use a suitable length of
seven core flex and insulated connectors should the
trailer wiring not be long enough.
If the trailer wiring does not conform to the
standard color code, identify each circuit as follows: (a) Locate the trailer earth wire.

218 Electrical System
Connect a jumper lead from the negative
terminal of a 12 volt battery to the earth wire. Connect a jumper lead from the positive
terminal of a 12 volt battery and connect each of the
trailer lamp wires in turn to the positive battery terminal jumper lead, noting the color of the wire
and the lamp circuit operated.

(3) After installation, connect the trailer plug to
the socket on the vehicle and check for correct lamp
operation.
