Abstract
An electrical heating arrangement for a motor vehicle comprises a heating resistor that is energizable directly by the power generator provided that within a network of consuming devices failure has been detected and also provided that essential elements of the network such as battery or engine temperature are within predetermined limits. Upon detection of a failure this error condition is optically indicated and the connection between the heating resistor and the generator is interrupted.
