Switch in position 2
Current goes to the windshield wiper motor (high speed)
and to relay 1 via connections 54 and 53b on the switch,
The current goes through the coil in relay 1 and the coil
attracts the relay contact to the lower position, where-
upon the coil in relay 2 is actuated and both relay con-
tacts are pulled downwards. Via the lower relay contact,
current is provided to the motor for the windshield wip-
ers, whereas the upper contact breaks the connection be-
tween terminals 87a and 87 to avoid short circuting when
the contact device in the motor interconnects connec-
tions 53 and 31b. A diode is connected before connec-
tion 3 on the windshield wiper motor and serves to pre-
vent current from going ‘‘backwards"’ through the extra
winding in the wiper motor and thus switching on the
headlight wipers when the windshield wipers are operat-
ing at low speed (position 1).
Switch in position 3
The same functions as in position 2, but the switch now
connects connections 54c with earth and by this means
both pump motors are engaged.
Switch in position 4
When the switch lever is moved towards the steering
wheel, a spring loaded contact is activated and switches
on both pump motors by earthing terminal 54c, At the
same time, the headlight wipers are also switched on in
that connection 85 on relay 2 is connected to earth via
relay 1 (the contact in this relay in the upper position)
and connection 54c.
Electrical connection and operation, as from model 1972
As from model 1972, the switch for wipers/washer has
been changed. The manouvre relay (1) and the diode have
been despensed with. Regarding the wiring, see group 371.
NOTE
For normal use of the wipers, a fuse for a maximum
current of 3 amp. is to be fitted in order to avoid
damage to the wiper motor if the wipers freeze on-
to the glass.
While testing the assembly (dry headlight glass), an
8 amp. fuse may be temporarily fitted.

then moving these in order to stretch the cords.
ADJUSTMENT OF CORD LENGTH
3. Check the pressure of the wiper blades on the head-
light glasses and make sure that the bushing does not
stick in the recesses in the front sheet. The pressure
of the wiper blades, measured in the parked position,
must not exceed 11 oz. (3 N, 300 p).
CRC 5.56 or similar is a suitable lubricant for the
bushings.
4. Check that the wiper shafts are Parallel (as seen from
the front). If necessary, adjust by removing the grille
plate and bending the bracket on the front sheet up-
wards or downwards.
5. Check that the central bushing is not loose and that it
does not follow the movement of the wipers. Lubri-
cate the central bushing with CRC 5.56 or similar.

Up to and incl. chassis No. 46.815 resp. 439.333 the stop
light switch is hydraulic and it is placed on the master
cylinder. .
As from chassis No. 46.816 resp. 439. 334, a mechani-
cally operated stop light switch has been introduced. This
switch is actuated directly by the brake pedal.
As from model 1968, a brake warning system has been
introduced. If the brake pedal stroke becomes abnormal-
ly big, the pedal actuates a switch located above it. This
switch then completes the circuit to a warning lamp in
the speedometer.

The switch is located by the gearbox and is actuated by
the gear shift mechanism.

LIGHTING RELAY
The lighting relay contains devices for flashing the high
beam and switching high beam and low beam. Function
(see Wiring diagram):
If the ignition switch (4) and the light switch (5) are on,
current will pass through relay coil (1). The coil contact
is pulled down and connects either high or low beam via
contact (3). Contact (3) can change position as it is me-
chanically influenced by the contact at relay coil (2).
This coil is connected with the headlight dimmer and
flasher switch (10) (i.e. the same lever as the direction in-
dicator switch), if either the ignition switch or the light
switch — or both — are switched off, the high beam signal
can be used. The contact at coil (1) is then in the upper

WIRING AND FUSES
WIRING
The cables and wires lead the current from the battery or
generator to the various items of consumer equipment.
In order to protect the wiring and to reduce the risk of
shorting, the wires are gathered into harnesses wherever
possible, i.e. a number of individually insulated wires are
carried in an enclosing plastic sheath.
The harnesses are divided into two groups, one at the
dash panel and in the engine compartment, and one run-
ning to the rear part of the car. Provided that the wiring
is fitted in strict accordance with the different wiring dia-
grams reproduced further on, removal and installation of
wires and cables should not present any difficulties. The
individual wires and cables in each harness are color-mark-
ed for ready identification in accordance with the numb-
ers given.
The cable connections are made with AMP connectors
and thus require no soldering.
Make sure that all cables and wires are properly connected,
thus avoiding unnecessary voltage drops and flashovers.
Make sure that the wire from the horn button is routed
so that it will not get torn off when the steering wheel is
turned.
lf frequent fuse burn out occurs, and if damaged insula-
tion is suspected, check the insulation of the harnesses
by testing. Bear in mind, however, that fuses will not burn
out if a short occurs before the fuse.
When installing new wiring, always check positively that
the rating of the selected wires and cables is adequate to
cope with the load involved, and make sure that the cables
are properly protected where they pass through panels
and at clamps.
FUSES
To protect wiring etc., from abnormal current intensities,
for instance in the event of a short circuit, and to reduce
the fire hazard involved by such occurrences, the electri-
cal system is provided with fuses, grouped in a block at-
tached to the R.H. side of the dash panel in the engine
compartment. In addition to the aforesaid fuses, there is
a3 amp. fuse for the headlamp cleaning device. This fuse
is located in a special holder.
One of the fuses are intended for the protection of extra
equipment or as reserve.
All the components included in the electrical system ex-
cept the headlight (as from model 1969), instrument
lighting and ignition system are fused. On the inside of
the fuse block cover is an identification text, showing
which items are protected by the individual fuses.

FUSE BLOCK
FUSE BOX, HEAD LIGHT CLEANING DEVICE
IMPORTANT |
When fitting a new fuse, take pains to secure good
contact. If wire fracture is suspected, check that the
fuse concerned makes good contact before taking
any further steps. Use a voltmeter for this check:
the maximum permissible voltage drop is 0.1 V.
