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.
With the ignition switch in position "II" (C094-1), 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.
