Hazard Warning Lamps: Description and Operation

DIRECTION INDICATOR/HAZARD WARNING LAMPS

DESCRIPTION

General
The direction indicator lamps are controlled via the LH column switch. The lamps will only operate when the ignition switch is in the 'ignition' position.

The hazard warning lamps are switched on and off by pressing the hazard warning switch mounted on the centre console. Hazard warning lamp operation is not dependant upon ignition switch position.

OPERATION

Direction Indicator Lamps
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 of the engine compartment fuse box (C0632) on an R wire. Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 8 of the passenger compartment fuse box (C0588) on a G wire. Fuse 8 (C0580) provides an ignition feed to the hazard warning switch (C0096) on a G wire. Current flows across the switch (C0096) to the flasher unit (C0580) on an LGK wire. The flasher unit is located in the passenger compartment fuse box and is earthed (C0587) on a B wire. The energised flasher unit (C0580) provides a feed to the indicator switch (C0036) on a LGN wire.

LH Turn
When the direction indicator switch is moved to the LH turn position, current flows across the switch (C0036) to the following:
^ The LH front direction indicator lamp (C0009) on a GR wire.
^ The LH side repeater (C0013) on a GR wire.
^ The LH rear direction indicator lamp (C0121) on a GR wire.
^ The instrument pack (C0233) on a GR wire.
^ The trailer pick-up (C0499) on a GR then Y wire.

All are earthed on B wires, except the trailer pick-up (W then B wire).
