This patent describes a two-battery power supply system for vehicles. The vehicles have a generator which includes an armature coil for generating three-phase alternating current, a field coil associated with the armature coil, a rectifier for converting the A.C. output of the armature coil into D.C., and a voltage regulator for setting the generated voltage of the armature coil at a constant value by controlling a current flowing through the field coil. The first battery is connected across the output terminals of the generator with a starting motor and an electric load is also connected in parallel with it. The patent also describes an ignition device, isolated from the first battery, with a second battery providing its power source. The final component described by the patent is that of a power source for charging the second battery to provide a stable voltage to the ignition device.
