Abstract
An engine starter system that predicts when starter failure is imminent. The engine starter system monitors engine starter crank speed, battery voltage and ambient air temperature. The crank speed, battery voltage and ambient air temperature are communicated to a controller which compares the crank speed for the measured battery voltage and air temperature to a predicted crank speed for the measured battery voltage and air temperature. If the crank speed is lower than the predicted crank speed, a signal is sent to an alarm.
