PCT No. PCT/EP97/00242 Sec. 371 Date Nov. 12, 1998 Sec. 102(e) Date Nov. 12, 1998 PCT Filed Jan. 20, 1997 PCT Pub. No. WO97/27660 PCT Pub. Date Jul. 31, 1997The present invention discloses an external wiring of a voltage controller in the electrical system of an automotive vehicle, wherein the power input of the voltage controller is connected by way of a dual diode to the main line, which is connected to the positive pole of the battery, and to the auxiliary line which is connected to the positive pole of the electrical system by way of an ignition switch. The auxiliary line is connected to a buffer capacitor. When the voltage on the main line breaks down, the supply of the power input occurs by way of the auxiliary line or by means of a current discharging from the buffer capacitor. When the voltage on the auxiliary line breaks down, the supply of the signal input is effected by way of the buffer capacitor which is dimensioned to buffer the power input.
