Headlamp washer

Headlamp washer

The headlamp washer comprises an additional pump (106) located on the windscreen and rear window washer fluid reservoir, to which two jets, mounted on the front bumper, are connected via pipes. The headlamp washers are activated by a timer (107) when the dipped beam or front and rear fog lamps are on, and when the windscreen washer pump is activated.

The headlamp washer is activated by operating the lever (L) located in the stalk unit (4).

Operation

The timer (107) is supplied on terminal (30) by a positive 12 V coming directly from the battery. It is protected by a 20 A fuse and is connected to the front left earth (39) through the terminal (31). When the dipped beam or front and rear fog lamps are switched on by the ring switch on the stalk unit, the timer (107) is supplied on terminal (56), preparing the system for operation.

Windscreen washer

When the lever (4) is moved backwards, horizontally (switch L), the windscreen washer pump (19) is supplied and at the same time an automatic wiping cycle is activated in accordance with the following logic:

About one second after the pump has been switched on, the windscreen wiper is switched on in continuous mode.

This condition remains for as long as the pump is supplied.

When the lever is released, the pump stops while the windscreen wiper remains on for about four seconds to finish wiping the windscreen.

Windscreen washer pump (19)

The windscreen washer pump is inserted directly in the fluid reservoir, located inside the front left mudguard.

Rear window wash/wipe

The pump is of the bidirectional type. It has two connectors on which are connected the two pipes that convey the washing fluid to the windscreen and rear window spray jets.

The direction of the fluid and so its destination depend on the direction of the rotation of the pump, which is determined by the position to which the lever (L) of the stalk unit (4) is moved. So if the lever is pushed forwards, horizontally, the pump is supplied sending the positive to the SN cable and the negative to the S cable.

The fluid is thus sent to the rear window and at the same time the rear window wiper (56) is activated until the lever (L) is released.
