DESCRIPTION OF OPERATION
Direction Indicators
Current is supplied to the direction indicator stalk switch via fuse 12 and then to flasher relay 23.
Current is supplied to terminal 30 of flasher relay 23 via fuse 22.
Current pulses then go from the flasher relay to the left-hand and right-hand direction indicator lamps.
In stalk switch positions L1 and R1 , the left-hand and right-hand direction indicator lamps respectively are connected as long as the stalk
switch is held in the appropriate position. In positions L2 and R2, connection takes place in the same way except that disconnection is
automatic when the steering wheel returns to the straight ahead position.
The two indicator lamps 47h (left-hand side) and 47i (right-hand side) are connected in parallel with the relevant direction indicator lamps
on the outside of the car.
Direction indicator lamps on a trailer, if any, are supplied with current via connector 258 (H8-5).
The car is also equipped with side direction indicator lamps 89LH (left) and 89RH (right).
The direction indicator bulbs are duplicated in the rear lights. If one bulb fails, the other bulb still continues to work but the flasher relay
will start to work faster.
Hazard Flashers
Current is supplied to terminal 30 of flasher relay 23 via fuse 22.
When hazard flasher switch 25 is activated, terminal B2 of flasher relay 23 will be connected to ground.
Current pulses then go from the flasher relay to the left-hand and right-hand direction indicator lamps, the two indicator lamps 47H and 47,
and to side direction indicator lamps 89LH and 89RH, which then start flashing.
When the switch is activated, the indicator lamp in the switch also lights up.
Direction indicators/hazard flashers on a trailer are supplied with current via connector 258 (H8-5).
FAULT DIAGNOSIS HINTS
Direction Indicators
The car 5 direction indicators are operative only when the ignition switch is in the Drive position.
1. Check that fuses 12 and 22 are intact and supplied with current.
2. Check that terminal 5 of direction indicator stalk switch 24 is supplied with current.

3. Check that current is supplied to terminals 49R and 49L of the flasher relay when the stalk switch is activated to turn on the
left-hand and right-hand direction indicators
4. Also check that the bulbs are intact and supplied with current.
5. Check the connectors, wiring harness and ground connections.
Hazard Flashers
The hazard flashers are always supplied with current via flasher relay 23.
1. Check that fuse 22 is intact and supplied with current.
2. Check that current is supplied to terminal 30 of flasher relay 23.
3. Activate the switch and check that terminal B2 of flasher relay 23 is connected to ground.
4. Check that the light bulbs are OK and supplied with current.
5. Check the connectors, wiring harness and ground connections.
