1. HOW TO CHANGE A ROAD WHEEL
(1) Ensure that the vehicle is on level firm
ground and clear of any passing traffic. (2) If necessary, switch on the hazard
flashers.
(3) Switch off the engine a nd place the transaxle
in the (P) Park position on automatic transaxle
models or in reverse gear on manual transaxle models.

(4) Apply the handbrake firmly and chock the
front and rear of the wheel diagonally opposite the
wheel being changed.
(5) Remove the spare wheel, tool kit and jack
located in the luggage compartment. (6) On vehicles equipped with full wheel covers,
remove the trim from the wheel. (7) Using the wheel spanner, loosen the wheel
nuts progressively in a diagonal sequence half a turn.
(8) Position the jack und er the jacking point
closest to the wheel being removed and raise the jack
until the head of the jack contacts the jacking point.
(9) Raise the vehicle slightly and check that the
jack is stable and vertical.

points. O indicates the jacking points and X indicates
the supporting points.
Chock the front and rear of the wheel diagonally
opposite the wheel being changed. View of the jack correctly installed to the rear jacking
point.

(2) Fault in the warning lamp wiring: Check and
repair the fault.

NOTE: When renewing bulbs ensure that a
new bulb of the correct wattage is used.

TURN SIGNAL LAMPS FLASH WEAKLY AND
AT GREATER THAN NORMAL SPEED

1. Faulty flasher unit: Check and renew the
flasher unit.
2. Front or rear bulb blown on the turn side:
Check and renew the bulb.
NOTE: If the flasher unit is to be renewed,
always try to obtain a genuine replacement
part.

HAZARD WARNING LAMPS DO NOT
OPERATE

Fuse blown: Rectify the fault and renew as
necessary.
Flasher unit faulty: Re new the flasher unit.
Hazard warning switch faulty: Renew the
switch.
Fault in the wiring circuit: Check and repair
the fault.
5. TEST EQUIPMENT AND SOME APPLICATIONS

Special Equipment Required:
To Make Test Lamp or Jumper Lead — Soldering
iron

When working on the electrical system, a test
lamp and jumper leads can be very useful to check
circuits.

TO MAKE A JUMPER LEAD
The minimum materials required to make a
jumper lead are one length of 4 mm wire and two
small alligator clips.

Grouping of materials to construct jumper leads of
various sizes.
Bare both ends of a suitable length of 4 mm
wire. Connect a small alligato r clip to each end of
the wire. Solder and tape the connections. Test the jumper lead for continuity by re-
moving one battery cable and connecting the lead
between the cable and the battery terminal. Turn the
ignition On and the dashboard warning lamps should
operate indicating a completed circuit through the
jumper lead. Remove the jumper lead from the circuit and
reconnect the battery.
NOTE: Make a few jumper leads of various
lengths using different sizes and types of
alligator and battery clips.

TO MAKE A TEST LAMP
Due to the extensive use of electronic components
in the electrical system, an LED (light emitting diode)
test lamp can be made from a suitable length of 3 mm
wire, an alligator clip, an LED, a 1/4 watt 560 ohm
resistor, a suitable case such as an old ball point pen
case and a length of rod or wire sharpened to form a
probe.

(1) Solder the length of wire to the K (cathode)

Electrical System 207

Disconnect the wiring connectors from the
rear of the combination switch.
Loosen the clamping screw located at the left
hand side of the combination switch. Push, turn and slide the combination switch
from the steering column. Installation is a reversal of the removal procedure.

REAR WINDOW DEMISTER
SWITCH/HAZARD WARNING LAMP SWITCH

To Remove and Install
Disconnect the negative battery terminal.
Using two small flat bladed screwdrivers,
carefully lever the edges of the switch forward to
release it from the instrument cluster surround.
Withdraw the switch from the surround and
disconnect the switch wiri ng at the connectors.
Installation is a reversal of the removal procedure.

DOOR LOCKS AND POWER WINDOW
SWITCHES

To Remove and Install
Disconnect the negative battery terminal.
Loosen the retaining screws securing the
armrest to the door. Using a small flat bladed screwdriver, care-
fully lever the front edge of the switch panel up and
maneuver the switch forward and away from the
armrest. Disconnect the wiring connector and remove
the switch from the armrest. Installation is a reversal of the removal procedure.

POWER MIRRORS AND INSTRUMENT
ILLUMINATION SWITCHES

To Remove and Install
Disconnect the negative battery terminal.
Using two small flat bladed screwdrivers,

vehicle.
carefully lever the edges of the switch forward to
release it from the fascia lo cated directly above the
fuse box.

(3) Withdraw the switch from the fascia and
disconnect the wiring.

Installation is a reversal of the removal procedure.
REAR WINDOW WIPER/WASHER SWITCH
To Remove and Install
Disconnect the negative battery terminal.
Using two small flat bladed screwdrivers,
carefully lever the edges of the switch forward to
release it from the instrument cluster surround. Withdraw the switch from the surround and
disconnect the wiring.
Installation is a reversal of the removal procedure.
