INTERIOR ILLUMINATION
DESCRIPTION
When the side lamps are switched on, the interior controls and gauges are
illuminated so they can be easily located during night driving. Interior
illumination is not controlled by the ignition switch.
OPERATION
Feed from the positive battery terminal is connected to fusible link 1 (C632-1)
of the engine compartment fuse box by a brown wire. Current flows through
fusible link 1 (C907-1) and onto the lighting switch (C041-1) on a brown wire.
With the lighting switch in either the side or head lamp position (C041-2),
current will flow to fuse 16 of the passenger compartment fuse box (C580-31)
on a red wire. Fuse 16 of the passenger compartment fuse box (C580-32)
supplies a feed to the following;
·Speedometer (C927-1 & C926-1) on a red/white wire.
·Fuel gauge (C924-1) on a red/white wire.
·Engine coolant temperature gauge (C735-1) on a red/white wire.
·Cigar lighter (C074-1) on a red/orange wire.
·Clock (C095-1) on a red/white wire.
All of the above are connected in parallel and are earthed on black wires.

INSTRUMENTS
DESCRIPTION
The vehicle relays information to the driver via the instrument pack. The
instrument pack contains lamps and analogue gauges. The colour of the lamp
denotes the severity of the information. Warning lamps are red, caution lamps
are orange, green and blue lamps indicate that a system is operating.
The analogue gauges relay information to the driver such as engine speed and
engine temperature.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C632-1) by a brown wire. Current passes through fusible link 1 and
fusible link 2 of the engine compartment fuse box, which are connected in
parallel. Fusible link 1 (C907-1) is connected to the lighting switch (C041-1) by
a brown wire, and fusible link 2 (C907-2) to the ignition switch (C028-1).
Fusible link 2 is also connected to fuse 2 (C580-3) of the passenger
compartment fuse box. Both are connected by brown wires.
With the lighting switch in either the side or main lamp position (C041-2),
current will flow to fuse 16 (C580-31) of the passenger compartment fuse box
on a red wire. Fuse 16 of the passenger compartment fuse box (C580-32) is
connected to the instrument pack (C233-3) by a red/orange wire and supplies a
feed to the side lamp warning lamp.
A permanent battery feed is also supplied from fusible link 2 of the engine
compartment (C907-2) to fuse 2 (C580-3) of the passenger compartment fuse
box. Fuse 2 (C580-4) is connected to the column switch (C036-7) by a purple
wire. When the column switch is closed (C036-5) a feed is sent to the main
beam warning lamp (C233-5) within the instrument pack on a blue/white wire.
The warning lamp (C233-2) is earthed on a black wire. 
						

							DESCRIPTION AND OPERATION
DEFENDER 97 MY4.33
With the ignition switch in position II (0C94-1), power is supplied to fuse 3
(C580-5) of the passenger compartment fuse box on a white wire. Fuse 3 of
the passenger compartment fuse box (C580-6) is connected to the instrument
pack. Current is supplied to the fuel gauge (C922-1) and the coolant
temperature gauge (C196-1) on green wires, which are connected in parallel.
The fuel gauge (C816-1) and the coolant temperature gauge (C815-1) are both
earthed on black wires.
With the ignition switch in position II (C094-1), power is also supplied to
header joint K109 (C285-17) on a white wire. Header joint K109 feeds the
following warning lamps;
·The glow plug warning lamp (C233-9) is fed by a white wire, and earthed
(C233-10) on a yellow/black wire via the glow plug ECU (C189-2).
·The diff lock warning lamp (C230-4) is fed by a white wire, and earthed
(C233-8) on a black/blue wire via the diff lock unit (C306-1).
·The ignition/no charge warning lamp (C230-4) is fed by a white wire, and
earthed (C230-5) on a yellow/brown wire via the alternator (C185-1).
·The low brake fluid warning lamp (C230-4) is fed by a white wire, and is
connected (C230-6) to the brake fluid level switch (C026-1) on a black/white
wire. When the switch is closed (C031-1) a path to earth is supplied on a
black wire.
·The transmission oil warning lamp (C687-1) is fed by a white wire, and is
earthed (C686-1) via the oil temperature switch (C219-1) on a slate/red
wire.

CLOCK
DESCRIPTION
The analogue clock is located towards the centre of the dash panel. The clock
is illuminated when the side lamps are switched on.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C632-1) by a brown wire. Current flows through both fusible link 1
and fusible link 2 of the engine compartment fuse box which are connected in
parallel.
Fusible link 2 (C907-2) is connected to fuse 2 (C580-3) of the passenger
compartment fuse box by a brown wire. Current flows through fuse 2 (C580-4)
to the clock (C232-1) on a purple wire. The clock is earthed (C210-1) on a
black wire.
Fusible link 1 (C907-1) is connected to the lighting switch (C041-1) by a brown
wire. When the lighting switch is in the side or main lamp position, current flows
through the switch (C041-2) and onto the clock (C095-1). This second feed to
the clock illuminates the integral bulb. The bulb is earthed (C210-1) on a black
wire.

IN-CAR ENTERTAINMENT
DESCRIPTION
The radio/cassette player operates when the ignition switch is in position I or
II. Signal output from the radio/cassette player is relayed to two loud
speakers. The radio/cassette display is illuminated when the unit is switched
on.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C632-1) by a brown wire. Current passes through fusible link 2 of the
passenger compartment fuse box (C907-2) and supplies the ignition switch
(C028-1) and fuse 2 of the passenger compartment fuse box (C580-3) with
current. Both are supplied by brown wires.
Fuse 2 of the passenger compartment fuse box (C580-4) supplies a constant
battery feed to the radio/cassette (C098-4) on a purple wire.

CIGAR LIGHTER
DESCRIPTION
The cigar lighter is located towards the centre of the dash panel. Pressing the
centre of the cigar lighter latches the heater element into the holder. With the
ignition in position II, power flows through the heating element of the cigar
lighter, causing it to heat up. When the heating element reaches a sufficient
temperature, the holder automatically releases the cigar lighter which can then
be removed for use.
The location of the cigar lighter holder is illuminated when the side lamps are
switched on.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C632-1) by a brown wire. Current passes through fusible link 1 and
fusible link 2 of the engine compartment fuse box, which are connected in
parallel.
Fusible link 1 of the engine compartment fuse box (C907-1) supplies a constant
battery feed to the lighting switch (C041-1) on a brown wire. When the lighting
switch is in the side or main lamp position, current flows through the switch
(C041-2) to fuse 16 of the passenger compartment fuse box (C580-31) on a
red wire. Fuse 16 (C580-32) is connected the cigar lighter illumination bulb
(C074-1) by a red/orange wire. The bulb is earthed (C089-1) on a black wire.
Fusible link 2 of engine compartment fuse box (C907-2) is connected to the
ignition switch (C028-1) by a brown wire. When the ignition switch is in position
II, current flows from the ignition switch (C094-1) to fuse 9 of the passenger
compartment fuse box (C580-17) on a white wire. Fuse 9 (C580-16) is
connected to the cigar lighter (C086-1) by a green wire. The cigar lighter is
earthed (C089-1) on a black wire.
