A starter solenoid switch according to the present invention includes a first and a second set of contacts that are disposed between a battery and a starter motor in parallel with each other. The first and the second sets of contacts are so configured that the second set of contacts is closed to supply a lighter electric current to the starter motor before the first set of contacts is closed to supply a heavier electric current to the same. The second set of contacts is composed of a second fixed contact and a second movable contact, one of which includes a low-resistance portion at one end thereof and a high-resistance portion that contains more carbon than the low-resistance portion. The low-resistance and the high-resistance portions are serially disposed along a conducting path of electric current from the battery to the starter motor, thereby ensuring reliability of the starter solenoid switch.

A system, capacitor having auxiliary cells, and associated methods for starting an engine is provided. The capacitor is an enhanced-power capacitor that provides enhanced cranking power. The capacitor is isolated from the battery and the rest of the engine's electrical system at preselected times. The capacitor is electrically connected to the alternator when the engine is running and is charged by the alternator. When the engine is not running, the capacitor is electrically isolated to prevent the capacitor discharging by powering accessory devices; the battery can power devices while the capacitor remains electrically isolated. During starting, the capacitor provides all the power supplied to the starter solenoid. If the battery is too weak to energize the electrical system during starting, an override allows the capacitor to provide power for all starting functions.

A solenoid for a vehicle starter comprises a pull-in coil and a hold-in coil positioned axially adjacent to the pull-in coil. A plunger is positioned within the pull-in coil and configured to move in an axial direction when the pull-in coil is energized.
