An indication device for a vehicle charging and generating system capable of informing the operator of the relation between the amount of power generation available and the amount of electric load applied, thereby enabling the operator to turn off unnecessary electrical loads to prevent the overdischarging of a battery. The indication device includes an AC generator having a field coil and driven by a vehicle engine, and a storage battery connected to an electric load and to the generator. A voltage regulator detects the output voltage of the generator or the voltage of the battery and has a power transistor 305 electrically connected in series with the field coil 102 of the generator to regulate the output voltage of the generator at a prescribed level. A converter 9 operates to convert the rate of electrical conduction of the power transistor into a corresponding voltage level, and an indication meter 10 is connected to the converter to display the utilized percentage of power generating capacity of the generator.
