Abstract
An electronic control for an electric cranking motor. A start switch controls energization of the cranking motor. The control has an up-down counter. When the start switch is closed the counter counts up and when the start switch is open the counter counts down. When the counter attains a certain count magnitude the cranking motor is deenergized and is prevented from being subsequently energized for a predetermined period of time to allow the cranking motor to cool-down. The rate that the counter is counted down is lower than up-counting rate.
