Direction indicators and hazard flasher system - operation and testing
Body electrical systems / Direction indicators and hazard flasher system - operation and testing


1 The direction indicators are controlled by the left-hand column switch.

2 A switch on the facia board operates all four flashers simultaneously. Although the direction indicators will not work when the ignition is switched off, the emergency switch overrides this and the flasher signals continue to operate.

3 All circuits are routed through the relay on the console and its fuse.

4 If the indicators do not function correctly, a series of tests may be done to find which part of the circuit is at fault.

5 The most common fault is in the flasher lamps, defective bulbs and dirty or corroded contacts or mountings. Check these first, then test the emergency switch. Remove it from the circuit and check its operation.

6 If the switch is in good order, refit it and again turn on the emergency lights. If nothing happens, then the relay is not functioning properly and it should be renewed.

7 If the lights function on emergency but not on operation of the column switch, then the wiring and column switch are suspect.
