Abstract
A voltage control apparatus for a vehicle-onboard electric generator in which wirings inclusive of connectors of the motor vehicle are much simplified to allow the manufacturing cost to be reduced significantly while making the trigger signal constantly available without difficulty even when abnormality takes place in association with the charge lamp. The voltage control apparatus includes a voltage control circuit (1A) for controlling a generated voltage of a vehicle-onboard electric generator (2), an external control unit (5A) for supplying a trigger signal to the voltage control circuit (1A), and a single signal line for electrically interconnecting a first terminal of the voltage control circuit (1A) and a first port of the external control unit (5A), wherein the external control unit (5A) is so designed as to output the trigger signal to the voltage control circuit (1A) by way of the single signal line, and wherein the voltage control circuit (1A) is so designed that upon occurrence of abnormality in the vehicle-onboard electric generator (2), the voltage control circuit (1A) informs the external control unit (5A) of abnormality occurrence status through the medium of the sing…
