A power module is connected to the starter, and generator of a motor vehicle. The power module is housed in a casing made of an insulative material. The power module includes a capacitor and an isolation circuit. The capacitor is connected to the starter when the ignition switch is closed to provide cranking current to the starter. The isolation circuit allows current to flow from the battery to the capacitor, but prevents current flow in the opposite direction. The capacitor is quickly recharged when the engine reaches an increased speed. Therefore, the capacitor is available to provide cranking current to a vehicle even when the vehicle repeatedly stops and starts over a short period of time.
