Abstract
In a battery charging control system for vehicles having an energization resistor connected to the output terminal of an auxiliary rectifier for the purpose of providing a current path from a battery through a key switch, a warning lamp and the energization resistor to indicate a failure of a generator by the lamp, an energization control circuit is provided to form the current path through the energization resistor only when a voltage developed at the output terminal of the auxiliary rectifier reaches a specified voltage level thus blocking the current path during initial excitation of the field coil of the generator.
