The circuit for the dipped beam headlamps
is operated by the steering column switch unit
H5
.
By placing the switch in the dipped beam
position, the line which supplies the headlamps
F10
(left)
and
F11
(right) is supplied controlled by the ignition.
Each circuit is protected by a fuse in the junction unit
B1
:
F5
for the right headlamp and
F4
for the left one.
With the dipped beam headlamps on, this
supply passes through the dipped beam headlamps maintenance relay/remote
control switch
J45
.
If the dipped beam and main beam headlamps
are switched, this supply is interrupted, but it is replaced by
the one supplied from pin 87 of remote control switch
J45
:
the signal for switching on the main beam headlamps - through the
steering column switch unit
H5
and the supply controlled
by the ignition (INT) for the line protected by fuse
F8
of the junction unit
B1
- energizes the relay (pin 85) which
switches the supply at the direct line (maxifuse J/B2 for
B5
)
which keeps the circuit for the dipped headlamps and the main beam
headlamps supplied.
The supply line for the right lamp - protected
by fuse
F5
- also acts as the go ahead signal for the headlamp
alignment (
See E3080 HEADLAMP AGLINMENT CORRECTOR
) and
the headlamp washer (
See E3022 HEADLAMP WASHER
).
