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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 113 words
A vehicle electrical system including a battery having first and second positive terminal and first and second negative terminals, a generator for charging the battery, and a voltage regulator for controlling the generator output, the generator output being applied between the first positive terminal and the first negative terminal, and all the loads of the vehicle which are susceptible to damage if the battery becomes disconnected being connected between the second positive terminal and the second negative terminal, at least one pair of terminals being constituted by a single post of stepped frusto-conical form providing two tapered portions separated by the step, the required connections being made to the two tapered portions respectively.
