ABSTRACT:
A power module is connected to the starter, alternator, and battery for an internal combustion engine. The power module includes one or more capacitors and delay timer. When the ignition switch closes, the battery of the starting system provides current to the starter motor, causing the starter solenoid to close the starter contacts, and bring a starter pinion gear into engagement with a flywheel ring gear. The delay timer does not allow the capacitor to immediately deliver current to the starter motor, but implements a short delay before the capacitor's current is released to the starter motor. This short delay increases the chance for full engagement between the starter pinion and the flywheel ring gear, thereby reducing the likelihood of milling when the starter motor provides torque to the starter pinion.
