Abstract:
A starter system including a motor, a solenoid assembly having a solenoid switch, a pinion rotated by the motor and moveable into an engaging position in which an engine may be cranked and the solenoid switch is closed to energize the motor from an electric power source, and relay switch regulated by a controller and closed to apply electrical power to the solenoid assembly for actuating the solenoid switch. The controller repeatedly opens and closes relay switch during a starting operation if sensed motor energization voltage monitored by the controller falls below a predetermined threshold level within a predetermined time period after electrical power is applied to the solenoid assembly, whereby electrical power applications to the solenoid assembly are automatically repeated during a starting operation to correct “click-no-crank” events and prevent prolonged power application to the solenoid assembly. A related method is also disclosed.
