ABSTRACT:
In a control device for an a. c. generator for an automobile, a collector potential detecting transistor for detecting potential at the collector of an alarm lamp actuating transistor is provided independent from a controlling transistor which functions to control the alarm lamp actuating transistor. When the collector potential detecting transistor detects an abnormal potential, it becomes conductive to turn off the alarm lamp actuating transistor to thereby prevent flowing of a short-circuit current.
