An engine cranking system and a method of cranking an engine are provided. The engine cranking system comprises an engine, cranking motor, and capacitor. The engine cranking system further comprises an electrical path interconnecting the cranking motor or a battery to the capacitor. The engine cranking system further comprises a control circuit coupled to the capacitor. The control circuit comprises a timer operative to track temporal information. The control circuit is operative to apply a control voltage that varies in response to the tracked temporal information. The control circuit further comprises a relay included in the electrical path. The relay is operative to switch, in response to the control voltage, between an open-circuit condition, in which the relay interrupts the electrical path, and a closed-circuit condition.
