Abstract
Abstract A vehicle electrical system incorporates a battery with first and second positive terminals and first and second negative terminals. The battery is charged by a generator, the output from which is controlled by a voltage regulator connected between the first positive terminal and the first negative terminal. Loads of the vehicle which are susceptible to damage if the battery becomes disconnected are connected between the second positive terminal and the second negative terminal.
