3. Lighting and light signalling system
The protection of the system circuitry by
means of the fuses has the following
peculiarities:
1) Separate protection of the clearance
light circuits at the sides:
• fuse (7) only protects the circuit of the
front and rear clearance lights of the left
side;
• fuse (8) protects the circuit of the
clearance lights of the right side as well as
that for illumination of the number plate and
instruments.
2) Separate protection of the road headlight
lower-beam circuit for each side:
• fuse (10) protects the circuit to the right
road headlight;
• fuse (9) protects the circuit to the left road
headlight.
3) Protection of the upper-beam circuits of
both headlights and pilot lamp of their ON
state by means of the fuse (6).
4) Protection of the circuits of the rear
working lights and cab lighting lamp by
means of the fuse (2) and protection of the
front working lights by means of the fuse
(13).
5) Protection of the circuits of the stop lights
by means of the fuse (1).
6) Protection of the circuits of the turn
indicators – by means of the fuse (12) and in
the fault signalling mode – by means of the
fuse (3).
Troubleshooting of the system
