    • The battery charging system includes a generator, a rectifier system with main diodes and exciter diodes as well as two terminals (B+, D-) for battery charging, at least one terminal (D+) for consuming points, a voltage regulator (14) for a generator output voltage, a charging control light (16) and a fail-safe device (15) structured to indicate faults and for protection from excess voltages. The fail-safe device includes an additional voltage regulating device (17) connected electrically to the generator and a relay (27) connected with the additional voltage regulating device. The fail-safe device also can include three voltage dividers (82, 83, 84; 70,71; 48,49) to provide different adjustable voltage thresholds, four Zener diodes (20 to 23) connected across terminals (D+ and D-) for limiting voltage, a pulse generator and a delay stage (19) structured and connected so that the additional voltage regulating device (17) regulates the generator output voltage, when an excess voltage occurs or a defective connection is present in the voltage regulator.
