Operation
When the ignition switch is in the drive position, the supply is taken from fuse 3, through seat-belt warning lamp 72 to the driver's seat-belt warning switch 70. The switch connects the warning lamp to earth, and the warning lamp will thus light up. When the seat-belt buckle is inserted into the lock, the switch will open the circuit and the lamp will be extinguished.

Seat switch 69 is connected in series to seat-belt switch 71 on the co-driver's side, and the seat switch will close when a load is applied to the seat. The warning lamp will thus only light up if a person is seated in the co-driver's seat and the seat belt is not fastened.

The seat-belt locks are illuminated by lamps 224 which are supplied directly from fuse 3.

Fault-tracing hints
The seat-belt warning lamp is operative when the ignition switch is in the drive position.

1. Check fuse 3 and check that the supply to it is live.
2. Check warning lamp 72.
3. Check seat-belt switches 70 and 71 and check that seat switch 69 operates satisfactorily.
4. Check the wiring, connectors and earthing.
