DESCRIPTION OF OPERATION
Seat-Belt Warning
With the ignition switch in the Drive position, current is supplied from fuse 3 via seat-belt warning lamp 72 to driver seat-belt warning switch 70. The switch grounds the warning lamp which then lights up.

When the seat-belt is inserted in the seat-belt buckle, the switch breaks and the lamp goes out.

Seat switch 69 is connected in series with passenger seat-belt switch 71 and closes when the seat is loaded. The warning lamp is only activated if the passenger seat is occupied and the occupant is not wearing the seat belt.

The seat-belt buckles are illuminated by two lamps 224 which are supplied with current directly from fuse 3.

Seat-Belt Warning With Buzzer And - Ignition Key Warning
The warning system alerts the driver if the seat belt is not fastened or if the car is left with the key in the ignition.

The system incorporates warning relay 82 which has a buzzer. When the ignition switch is in the Drive position, the relay is supplied with positive current via fuse 13.

Seat-Belt Warning:
When the ignition switch is in the Drive position, positive current is also supplied from fuse 3 via seat-belt warning lamp 72 to the warning relay.

If the belt is not fastened, the relay will be grounded by driver seat-belt warning switch 70. The warning lamp then lights up at the same time as the buzzer sounds. When the seat-belt is inserted in the seat- belt buckle, the switch opens and the light and buzzer go off.

Ignition Key Warning:
As long as the key remains in the ignition switch, current will be supplied from ignition switch terminal B to the warning relay.

If the key is still in the ignition switch when the driver's door is opened, door switch 54 will close. This grounds terminal 1 and causes the buzzer to sound.

FAULT DIAGNOSIS HINTS
Activation of the seat-belt and ignition key warning takes place when the ignition switch is in the Drive position.
1. Check that fuse 3 is intact and supplied with current.
2. Check warning lamp 72.
3. Check that seat-belt switches 70 and 71 and seat switch 69 are in proper working order.
4. In regard to the seat-belt and ignition key warning with buzzer, also check that fuse 13 is intact and that current is supplied to the relay.
5. Check the wiring harness, connectors and ground connections.
