Abstract
A starter for a motor vehicle engine is equipped with a device for cutting off the operation of the starter as soon as the engine is running by itself. The device detects the voltage or current waves in the power supply to the starter, and stops the starter when these waves disappear. At each new wave in the power supply signal, a monitoring period is generated, having a duration which decreases as the frequency of the waves increases, the starter being stopped when no new wave is detected in the last monitoring period.
