The signal for activating the side lights reaches the ignition
switch
H1 (STAZ) when the steering column switch unit H5 - connector B pin 6 - is in the appropriate position:
it is a supply controlled by the ignition (INT) for the line protected
by fuse F8 of the junction unit B1.
Alternatively - with the key in the PARK
position - the supply arrives directly from the battery (IGN maxifuse
for
B5).
From switch
H1 (POS) the supply
is sent to the various side lights through the lines protected by
fuses F2 and F3 for the junction
unit B1.
The former protects the circuits for the
right front
F11, left rear F30 and right
number plate F51 lights.
The second
protects the circuits for the left front
F10, right rear F31 and left number plate F50 lights.
At the same time, the side lights on warning
light is supplied inside the instrument
E50 - pin 1 for
connector B -, whilst pin 3 for connector A of E50 acts
as an earth.The same signal dims the instrument light
with the lights switched on.
