This patent describes a vehicle battery charging system having a battery for outputting a battery voltage, a series combination of a key switch and a large lamp, a current generator having stator windings for outputting a stator output voltage, a field winding and a full-wave rectifier, and a voltage regulator. The above mentioned components are arranged to control the field current through the field winding in accordance with a predetermined voltage. The voltage regulator comprises: a series combination including a semiconductor switch means and a resistor connected between the terminal and ground. The semiconductor switch means are activated at least when the key switch is opened in order to bypass leakage current therethrough.
