The power supply system (Fig. 1) serves to power consumers when the engine is running
The sources of electricity are two batteries 6 connected in series, a generator set 2 connected in parallel with the batteries.
The negative terminal of the batteries is connected to the car body via remote-controlled ground switch 7.
The circuit is equipped with relay 1, which breaks the circuit of the generator excitation winding when the EPI is operating.
In addition, when the instrument switch key 13 and the starter are in the operating position, current is not supplied to button 8 of the remote mass switch, which prevents accidental switching off of the mass while the engine is running (switching off the batteries is possible only after disconnecting the generator from the electrical system by installing the instrument switch key and starter to neutral position).
Below are the electrical diagrams of these systems and their descriptions.
On the diagrams next to the symbolic image of the elements of electrical equipment, the numbers of the connected wires are shown, the letters indicate their color: B - white; G - blue; F - yellow; Z - green; K - red; KCH - brown; O - orange; P - pink; C - gray; F - purple; H - black.
