2. TO CHECK IGNITION AND ELECTRICAL SYSTEM
(1) Switch on the ignition and check for warning
lamp illumination on the dashboard. (2) Operate the starter and check that the starter
rotates the engine at a steady speed.
(3) Switch on the headlamps and check for good
light intensity. Should the lamps not illum inate or the starter
motor not turn the engine, carry out the following
steps:
(a) Remove the battery terminals and clean both
terminals and posts. Connect the terminals and where
applicable tighten firmly but not excessively.
(b) Check that the earth lead from the battery to
the engine or body frame is not broken and that the
connections are clean and secure. . (c) Check that the lead from the battery to the
starter motor or starter solenoid is intact and has a
clean and secure connection.
Ensure that the battery posts and terminals are clean.
(d) Where necessary carry out repairs to (b) and
(c).
Repeat the check procedur e. Should the starter
motor still not operate, or the lamps not illuminate,
one or more of the following faults may be the cause:
No starter motor operation or lamps: Battery flat
or defective.
Lamps illuminate but no starter operation: Starter
motor drive jammed in mesh with flywheel ring gear.
Starter motor or solenoid defective. Ignition/starter
switch faulty. On automatic transaxle models, faulty
neutral safety switch.
Lamps dim and starter operation sluggish: Dis-
charged battery or fault in starter motor. Battery flat
due to broken fan belt or de fective alternator. Faulty
battery due to cell breakdown.
NOTE: Electronic ignition systems can pro-
duce dangerously high voltages in both the
primary and secondary circuits. For this
reason, extreme care must be taken when
performing these checks. When disconnect-
Securely earth the body of a test spark plug to check
for sparks at the spark plug leads.

78 Cooling and Heating Systems
The air conditioner operates only when the engine
is running as the compressor is belt driven from the
engine.
Operating the air conditioner with the tempera-
ture control raised to a hot setting will produce
dehumidified hot air which is particularly useful for
demisting the vehicle glass.
Maximum cooling is achieved by operating the air
conditioner with the temperature control lowered
fully to the coldest setting . Operate the fan at high
speed when using the coldest temperature setting to
avoid forming ice on the evaporator.

2. DESCRIPTION
The clutch consists of a single, dry, driven plate
assembly, splined to slide on the transaxle input shaft.
A diaphragm spring type pr essure plate assembly is
bolted to the engine flywheel.
The driven plate is sandwiched between the
pressure plate and the flywheel and transmits the
drive from the engine to the transaxle.
Cushion rubbers are interposed between the hub
of the driven plate assembly and the plate friction
surfaces in order to cushion the drive.
The release mechanism is actuated by the clutch
pedal through a cable to the release lever and bearing.
Operation of the clutch pedal moves the release
lever which pushes the release bearing into contact
with the diaphragm spring fingers, forcing the dia-
phragm centre towards the flywheel. When the outer
edge of the diaphragm deflects, the clutch is caused to
disengage.
Clutch pedal free play is adjusted at the release
lever end of the clutch cable.
Clutch pedal height is adjusted at the pedal stop
on the pedal mounting bracket located under the
dashboard.

wiper blade is horizontal to the lower edge of the edge
of the rear window when in the Park position.
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.

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.
