Functional Description
The instrument panel C10 is illuminated by powering a series of inserted lamps; this supply is routed through a dashboard lighting dimmer rheostat B16 which permits the lighting intensity to be adjusted to the desired level.
The rheostat B16 is powered by battery voltage, through relay 164 and fuse F6 (10A) of the fusebox G1, when the sidelights are switched on using the switch on the lever group B68. Intensity is regulated by the negative signal which reaches the "key operated" supply instrument panel lamps.
