Abstract
In a voltage regulating system, a transistor switching circuit is connected to a voltage sensing circuit which detects a battery voltage and to a lamp. And at least when the voltage sensing circuit becomes disconnected from the battery, the transistor switching circuit is switched on to energize the lamp to inform a driver of the disconnection.
