E3070 Cigarette lighter/power socket

Description

There are three ashtrays in the car: one is in the centre of the dashboard, and two are in the rear doors.

The front ashtray is lit when the side lights are on; it houses a standard power point; the ring round the power point is lit with the side lights on. The cigar lighter resistance is located in the socket, but it can be used for connection to other instruments or equipment (provided they operate at 12 V). To operate the cigar lighter, simply press the knob: after a few seconds it pops out automatically, ready for use.

The socket has a heat protection device: if devices with high energy absorption are connected, this protection cuts off the supply.

The current socket circuit is protected by a special fuse and is operated by the relay which is excluded when the ignition is switched on and is located in the junction unit.

The sockets are only supplied when the ignition is switched ON.

Description of operation

The power socket / cigarette lighter P50 is supplied (at pin 2) by the line controlled by the ignition (INT/A) for the relay R1 protected by the fuse F15: both are housed in the junction unit B1.

Pin 3 of socket P50 provides the earth from C20.

The ring nut for the power socket is lit up (at pin 1) when the side lights are on by means of the line coming from the steering column switch unit H5 switch and is protected by the controls illumination fuse B11 up to 2/99 or fuse F4 of the additional fuse unit B98B from 2/99.

The same supply line with the side lights on also lights up the ashtray light G35.
