DIRECTION INDICATORS AND WARNING LIGHTS
WARNING LIGHTS
A supply voltage is applied to connection point 6
of warning-light switch C765 through fuse E108.
By activating the warning light/direction indicator
switch the supply voltage is applied to point 37 of
the CTE-2.
The CTE 2 now supplies a square-block voltage
through point 4 to lights C014, C016 and C018 (all
on the left side) and through point 31 to C015,
C017 and C019 (all on the right side), as a result
of which these lights start blinking simultaneously.
The warning lights also function if the contact is
not activated.
CTE-2 (point 35) also supplies a square-block
voltage to warning light/direction indicator switch
C765 ( to point 1), causing the LED in the switch
to blink also.
DIRECTION INDICATORS
Left
If the direction indicator switch (C775) is activated
to the left (connection between points 3 and 2),
the supply voltage is passed on to point 53 of the
CTE-2 through wire 2002. Subsequently the
CTE-2 supplies a square-wave signal through
point 4 to C014, C016 and C018 (left direction
indicators) and through point 2 to connector
socket A000 pin 3 (in the case of an FA) or A002
pin 3 (in the case of an FT). Every time a pulse is
supplied to point 4 of the CTE-2, the lights will
blink briefly.
Right
If the direction indicator switch (C775) is activated
to the right (connection between points 3 and 1),
the supply voltage is passed on to point 24 of the
CTE-2 through wire 2001.
Subsequently the CTE-2 supplies a square-wave
signal through point 31 to C015, C017 and C019
(right direction indicators) and through point 30 to
connector socket A000 pin 5 (in the case of an
FA) or A002 pin 5 (in the case of an FT). Every
time a pulse is supplied to point 31 of the CTE-2,
the lights will blink briefly.
The CTE-2 (points 7 and 34) also supplies a
signal to the instrument panel.
If the direction indicator installation functions
properly, the lights for the truck (2/202) and the
trailer (8/202) will light up.
