2. Check the bulbs and check that the supply to them is live.
3. Check the connectors, cable harnesses and earth connections.

47A Fuel gauge and 47B Fuel reserve warning lamp
Operation
The fuel gauge and the fuel reserve warning lamp keep the driver informed of the fuel level in the tank. When the ignition switch is in the drive position, a positive supply (+15) is taken from fuse 22 to:

- Fuel level gauge 47A in the combined instrument and then through a 3-pole connector (57) to fuel level transmitter 46 in the fuel tank to earth, and

- Fuel reserve warning lamp 47B and then through the fuel level transmitter in the fuel tank to earth.

Fuel level transmitter 46 adjusts the voltage so that the fuel gauge reading will correspond to the level sensed by the transmitter float in the tank.

When the fuel content of the tank has dropped to about 7 dmj3 (liters) or less, the fuel reserve warning lamp will be earthed through the transmitter and the lamp will light up.

Fault-tracing hints
The fuel gauge and the warning lamp for the fuel reserve will be operative when the ignition switch is in the drive position.

1. Check fuse 22 and check that the supply to it is live.
2. Check the bulb and check that the supply to its terminals in the combined instrument is live.
3. Check that the terminals of the fuel gauge and the fuel level transmitter are live.
4. Check the connectors, cable harnesses and the earth connection of the fuel level transmitter.

Resistance of the fuel level transmitter
- 2.4 - 8.0 ohm when the tank is full
- 63.3 - 67.5 ohm when the tank is empty

47C Temperature gauge
Operation
The temperature gauge shows the engine coolant temperature.

When the ignition switch is in the drive position, coolant temperature gauge 47C is supplied (+15) from fuse 22. The other terminal of the gauge is earthed via coolant temperature transmitter 45.

Changes in the coolant temperature will affect the resistance of the transmitter, and the gauge will thus show the prevailing engine temperature.

Fault-tracing hints
The temperature gauge will be operative when the ignition switch is in the drive position.

1. Check fuse 22 and check that the supply to it is live.
2. Check that the supply to the temperature gauge is live.
3. Check that there is no open circuit in transmitter 45.
4. Check the connectors, cable harnesses and earth connections.

Resistance of the temperature transmitter: 51.2 ± 4.3 ohm at +90°C (194°F)

47D Oil pressure warning lamp
Operation
The oil pressure warning lamp is intended to warn the driver that the engine oil pressure is below the predetermined value.

Lamp 47D in the combined instrument is supplied (+54) from fuse 7, via red 29-pole connector 152B.

If the lubricating oil pressure should drop below 0.3-0.5 bar, oil pressure transmitter 44 will close and the lamp will light up.

Fault-tracing hints
The oil pressure warning lamp will be operative when the ignition switch is in the drive position.

1. Check fuse 7 and check that the supply to it is live.
2. Check the bulb and check that the supply to its terminals in the combined instrument is live.
3. Disconnect the cable from the oil pressure transmitter and earth it. If the lamp lights up, the circuit is unbroken.
4. Check the connectors, cable harnesses and the earth connection of the oil pressure transmitter.

47E Charging warning lamp
Operation
The charging warning lamp informs the driver of whether or not the alternator is charging.

When the ignition switch is in the drive position, a positive voltage will be supplied via fuse 7 and red 29-pole connector 152B to charging warning lamp

47E in the combined instrument. The other side of the lamp is connected to alternator 2.

When the alternator is not rotating or when it is not charging the battery for any other reason, the circuit for the charging warning lamp will be earthed through terminal D+ on the alternator, and the lamp will light up.

When the alternator is charging, terminal D+ will be at the same voltage as the supply from the fuse. The same voltage will then be applied to both terminals of the warning lamp, and the lamp will therefore be extinguished.

Fault-tracing hints
1. Check fuse 7 and check that the supply to it is live.
2. Check the bulb in the warning lamp.
3. Check the connectors, cable harnesses and the earth connections of the alternator.
4. Check that terminal D+ of the alternator is live.

47F Brake fluid level warning lamp
Operation
The brake fluid level warning lamp is intended to warn the driver that the brake fluid level in the reservoir is low. Its operation can be checked by means of a button on the brake fluid reservoir.

When the ignition switch is in the drive position, lamp 47F is supplied (+15) from fuse 22, via red 29-pole connector 152B.

The other side of the lamp is connected to brake warning switch 42, via black 29-pole connector i52C.

If the fluid in the brake fluid reservoir should drop to an inadmissibly low level, switch 42 will close and the warning lamp will light up.

Lamp test
When the ignition switch is turned to the start position, terminal 15 of ignition switch 20 supplies pin 9 of lamp 47F, and the anode of the diode in the combined instrument.

In the start position, the supply from +54 will be open, so that the cathode of the diode in the combined instrument will be earthed via pins 7, 9 and 8 of lamp 47E, and via alternator 2. The diode prevents reverse flow of current.

Fault-tracing hints
The brake fluid level warning lamp will be operative when the ignition switch is in the drive position.

1. Check the brake fluid level warning circuit by pressing the button on the brake fluid reservoir. The circuit should close and the lamp should light up.
2. Check fuse 22 and check that the supply to it is live.
3. Check the bulb and check that the supply to its terminals in the combined instrument is live.
4. Check the connectors, cable harnesses and the earth connection.

47M Handbrake warning lamp
Operation
The handbrake warning lamp warns the driver that the handbrake is applied.

Lamp 47M in the combined instrument is supplied (+15) from fuse 22 via red 29-pole connector 152B. As long as the handbrake is applied, handbrake switch 43 will be closed and the lamp will stay alight.

Lamp test
When the ignition switch is turned to the start position, terminal 15 of ignition switch 20 will be live. Current will flow to pin 11 of lamp 47M and the anode of the diode in the combined instrument.

When the switch is in the start position, the supply from +54 is opened, and the cathode of the diode in the combined instrument is therefore earthed via pins 7, 9 and 8 of lamp 47E and alternator 2.

If lamp 47M is in good condition, it should then light up. Correct indication will be obtained only if the handbrake is not applied. The diode prevents reverse flow of current.

Fault-tracing hints
The handbrake warning lamp will be operative when the ignition switch is in the drive position.

1. Check fuse 22 and check that the supply to it is live. Check also fuse 7.
2. Check the bulb and check that the supply to its terminals in the combined instrument is live.
3. Disconnect the cable from the handbrake switch and earth it. If the lamp lights up, the circuit is unbroken.
4. Check the connectors, cable harnesses and the earth connection of the handbrake switch.
