DESCRIPTION OF OPERATION

The window raiser relay, located in junction unit B1 (connector E) , controls window raiser operation.

The window raiser relay is supplied by direct line from the battery through power supply fuse B50 that protects several optional services.

The relay coil is supplied through the ignitioon switch power supply(INT/A) from the line of fuse F12- of junction unitB1,and is always earthed : thus the relay is always energised by (INT/A).

In this way the line protected by fuse F2of junction unit B1 supplies the two switches H42 (left window raiser), H43 (right window raiser) and the relevant LEDs that light up the switches.

When the switches are activated power supply and earth are delivered to the leftN60 or right N61 window raiser motor.; reversing the signals according to the contact the direction of motor rotation is defined.
