A battery charging system includes an alternator, a main rectifier for charging the battery, and an auxiliary rectifier for supplying current to the alternator field winding under control of its voltage regulator 20. A first transistor switch is sensitive to under voltage to illuminate a first warning light and a second transistor switch is sensitive to over voltage to illuminate a second warning light. The two transistor switches are cross-connected so that failure of either light causes illumination of the other. |
