11. FRONT AND REAR FOG LIGHTS
There are three possible situations:
-
Rear fog lights only.
-
Front fog lights only.
-
Front and rear fog lights.
REAR FOG LIGHTS (standard)
The rear fog lights can only be activated in
combination with the dipped beam.
If the lighting switch (C622) is switched into the
”dipped beam” position (connection between the
contacts 2 and 4), a voltage is applied through
wire 1101, switch C622, wire 2110 and the diode
for rear fog light/dipped beam (D600), to switch
rear fog lights with contact 3 of transfer relay
(C863). A voltage is also applied to contact 6 of
switch C863 and to contact 5 of the front fog
light switch (C728) through the diode for the light
switch (D609) and wire 2100.
The rear-light/side light (G000) is energised.
This will cause the contacts 30 and 87 to be
closed. A voltage is applied to the position,
marker and tail lights on the left and right-hand
sides of the vehicle respectively through the fuse
for the rear left side-light (E000) and the fuse for
the rear right side-light (E001).
If switch C863 is engaged (connection between
contacts 3 - 1 and 6 - 2), a voltage is applied to
connection point 1 of the rear fog light transfer
microrelay (G392) and to connection point 85 of
the rear fog light relay (G005). Both relays are
energised.
A voltage is applied to the left and right rear fog
lights through the rear fog lights fuse (E010) and
contacts 30 and 87 of relay G005. The rear fog
lights will now come on.
Microrelay G392 ensures that a connection is
made between contact 2 of switch C863,
through wire 2171, contacts 3 - 5 of relay G392
and wire 2150 at connection point 85 of the rear
fog light relay G005. This relay will remain
activated until the connections 3 - 7 and 6 - 8
are made for a short time with the aid of switch
G863. That is when the coil of relay G392 will be
de-energised. The connection between contacts
3 - 5 will be broken at the same time, so that
G005 will be de-energised as well. The rear fog
lights will now go out.
