FF 7294 R.ND 140 "ELECTRICAL GENERATING SYSTEM, PARTICULARLY FOR AUTOMOTIVE USE" ABSTRACT To prevent unusually high or low voltage output from an automotive-type alternator, in case of failure of connection from the alternator rectifier output to the automotive vehicle battery, a connecting network is provided connecting an auxiliary alternator output terminal to the voltage sensing circuit to control the voltage sensing circuit to in turn control the field current to the alternator to prevent excessive output voltages. Addition- ally, a further voltage sensing circuit is connected to the auxiliary terminal to provide limited energization to the field for self-excitation of the generator if the vehicle engine, driving the generator is started, for subsequent transfer of control to the main voltage sensing circuit, but to prevent continuous field current flow at full field current value to prevent burnout of the field in case the engine is not started, but the main vehicle switch, typically the ignition switch, is left closed. -1-
