2.7. Electrical system
The electric system of the trailer has been designed for feeding from tractor’s 12V direct
current source. The trailer is equipped with additional working light inside the body. The
switch for working light is mounted on the front left side of the chassis. Working light is
adapted for feeding from the current of trailer’s position lights, thus it works only when
lights of tractor-trailer are switched on. The scheme of the electric installation is
provided in
Figure 10
. System can be connected to the tractor by means of standard
electric plug 7PIN 12V ISO 1724. The description of contacts of appropriate 7PIN
