Operation

Operation

Adjustment is electrical and is effected when the dipped beam headlamps are switched on. The movement is achieved by two motors (43-44) mounted directly on the light clusters. The control (45) is a potentiometer controlled by a knob located on the dashboard, which can be set to four different positions corresponding to the four positions that can be assumed by the lights clusters. The wiring diagram shows the connections of the various devices which constitute the system.

The system is supplied by a voltae of 12 V coming from the ignition switch, and is protected by the fuse (F5) located on the fuse and relay unit (4). The actuator consists of a motor on which a potentiometric position transducer is mounted, and an electronic control unit.
