ABSTRACT:
A device for supplying voltage to at least one consuming device in a motor vehicle including two parallel generators, two voltage regulators associated with each of the generators, two batteries each connected with one of the voltage regulators, a starter switch connected with at least one of the batteries and the voltage regulators, a charge control lamp for signalling connected with the starter switch and the voltage regulators, switching device for electrically connecting and disconnecting the consuming device or devices, and devices for controlling the voltage regulators so that during starting the charge control lamp indicates starting and the switching device disconnects the consuming devices and if a defect occurs in either generator-voltage regulator system, the charge control light lights and the consuming device or devices is (or are) supplied with current, even if, for example, one of the generators fails. The device for supplying voltage advantageously includes a switch device having four diodes, the anodes of two diodes (D1,D2) being connected with each other and the charge control lamp and the cathodes of the two diodes (D1,D2) being each connected to a different voltage regulator, and the cathodes of the other two diodes (D3,D4) being connected with each other and the switching device (13).
