The headlamp washer
J50
is supplied
(pin P) by the direct line from the battery through the headlamp
washer fuse
B12
and the maxifuse
J/B2
of
B5
.
If the windscreen washer switch is operated,
the steering column switch unit
H5
sends a signal which
reaches the headlamp washer timer
J50
(pin S): this is a
line controlled by the ignition (INT/A) coming from the steering
column switch unit
H5
- pin 3 of connector D - supplied
by the relay
R1
, protected by fuse
F14
: both are
housed in the junction unit
B1
.
The supply for the relay
R1
comes
from the direct line of the maxifuse
J/B1
of
B5
,
whilst the coil is supplied by the line (INT/A) protected by the
fuse
B26
(
See E3020 WINDSCREEN WASH/WIPE
).
With the dipped headlamps switched on, a
go ahead signal reaches pin 56 of
J50
from the line for
fuse
F5
which supplies the dipped headlamps. (
See E2011 DIPPED HEADLAMPS
).
When there are both signals at pins S and
56, the relay, inside the device
J50
which supplies the
electric headlamp washer pump
N25
with impulses of about
half a second, is energized for a certain time.
