Abstract
A generation control apparatus for a vehicle generator detects the output voltage of an excitation current supplying rectifier circuit of the generator. When the output voltage is lower than a predetermined value, a switching element is turned on and a current for operating an indicator lamp is caused to flow through a resistor connected to the switching element, thus detecting a break in the generator circuit.
