Left-hand drive cars prior to car serial number 6000
To renew a faulty printed circuit proceed as follows.
1. Disconnect the battery.
2.
Disconnect the cables adjacent to the relays
at the 'Lucar' connectors and note the position of
each for fitting.
3.
Disconnect the 5-way plug situated at the
centre of the printed circuit.
4.
Remove the four self-tapping screws securing
the printed circuit; then remove the circuit from
the car.
Printed circuit-To fit
Cars prior to Car Serial Number 6000
When fitting the new printed circuit, it will be noted
that the holes used to retain it to the stowage com-
partment are off-set. The circuit can be fitted one
way only. Ensure that the layer of 'Leatheroid'
insulator is fitted between the relays and printed
circuit to eliminate electrical shorting.
It is necessary to align the distance tubes to the
securing screws to facilitate correct fitting and
enable the screws to engage the
'
Spire' nuts.
Further fitting is achieved by reversing the pro-
cedure given for removal.
Should difficulty be encountered during the above
procedure,
i.e. with the distance tubes or
'
Spire'
nuts, an alternative procedure in addition to that
previously described for removing the small trim
panel, is as follows.
1.
Remove the seat cushions and lift up sufficient
carpet to expose the four feet of the stowage
com-
partment/occasional seat assembly.
2.
Disconne.ct the wiring socket situated adjacent
to each seat mechanism and remove the clip securing
the wiring loom to the seat mechanism.
3.
Disconnect the incoming cables at the front of
the stowage compartment.
4.
The two brown cables have 'Lucar' connectors,
the black cable and green cable have snap connector
fittings.
5.
Fit the stowage compartment/occasional seat
by reversing the procedure given for removal.
Seat printed circuit-To remove
Cars after Car Serial Number 6000
To renew a faulty printed circuit proceed as follows.
1.
Disconnect the battery, and remove the left-
hand triangular trim pad on the console.
2.
Disconnect the cables adjacent to the relays
at the
'
Lucar' connections and note the position of
each to facilitate fitting.
3.
Disconnect the 5-way plug situated at the centre
of the printed circuit.
4.
Carefully lift the printed circuit out of its
retaining slot and withdraw through the left-hand
side of the console.
Relays-Electrically operated windows
Four
'
Lucas'
6
R.4
relays are incorporated in the
wiring circuit for the electrically operated windows.
The relay is rubber mounted on each door frame,
adjacent to one of the apertures behind the trim and
dust cover.
Relays-To renew
The relays are sealed units and if a failure occurs
the faulty relay should be renewed.
1. Disconnect the battery.
2.
To gain access to a relay; remove the door
handles, door trim and dust cover as described in
Chapter S
-
Body. This will expose the window lift
mechanism and relay fixing positions.
3.
When working on the rear doors, working space
is improved if the window glass is raised to its
fullest extent. If the window is partly or even fully
lowered, due to the window lift being inoperative,
there is still sufficient room for the hand to remove
and renew the
faulty relay.
4.
The small apertures adjacent to the relays are
not sufficiently large to enable the relay to pass
through but are sufficient to enable the
'
Lucar'
terminals to be disconnected and to identify the
cable colours and terminal identification marks for
correct assembly.
5.
When fitting the door trim, ensure that the
water shield is fitted and that the door dust
covering is sealed around its edges, if not, apply
'
Dunlop' S81 adhesive to effect the sealing.
Relays-Stoplamp failure warning
(where fitted)
One relay is fitted adjacent to the rear of each rear
lamp cluster. The relays are rubber mounted to the
body frame behind the side panels of the luggage
compartment.
The function of each stop lamp relay is to
indicate the
fallure of a stop lamp bulb.
With the ignition
'ON',
the facia lamp performs
two functions; it indicates to the driver that the
handbrake is applied, or of a stop lamp bulb
failure
when the brake pedal is applied with the handbrake
off.
Relays-To renew
When a failure occurs, the relays must be renewed.
1.
Disconnect the battery.
2.
Fold-back the luggage compartment trim and
disconnect the cable
'
Lucar' connectors from the
faulty relay.
3,
Note the cable colours to relay terminal
positions to facilitate correct fitting.
4.
Remove the rubbers which secure the relay to
the body frame.
