CLOCK
DESCRIPTION
The analogue clock is located towards the center of the dash panel. The clock is
illuminated when the sidelights are switched on.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment fuse box
(C632-1) by the brown wire. Current passes through fusible link 1 and fusible link 2 of
the engine compartment fuse box which are connected in series. Fusible link 2 of the
engine compartment fuse box (C574-3) provides a permanent power supply to the
analogue clock (C949-1) on the purple wire. The clock is grounded (C950-1) on a black
wire.
Illumination
The analogue clock has illumination which operates with the sidelights. Power from
fusible link 1 of the engine compartment fuse box passes through fusible link 4 of the
engine compartment fuse box (C573-2) and feeds the lighting switch (C41-1) on the
brown wire. The lighting switch (C41-2) is connected to fuse 11 of the passenger
compartment fuse box (C581-1) by the red wire. When the lighting switch is turned on,
power is supplied through fuse 11 (C581-2) to the dimmer circuit header joint (C285-7)
on the red/black wire - (See interior illumination). Power flows through the dimmer
circuit (C285-16) to the clock illumination (C948-1) on the red/white wire. The clock
illumination is grounded on a black wire.
