ABSTRACT:
An electrical distribution system for a motor vehicle comprises an engine, an electrically-conductive structural portion of the vehicle and a battery having a positive terminal and a negative terminal. The system also includes a starter motor having an electrical current return electrically coupled to the engine and an electrical generator having an electrical current return electrically coupled to the engine. Also, the system comprises an electrical current return path from the structural portion to the engine and an electrical current return conductor electrically and mechanically coupled between the engine and the structural portion. In addition, the system contains a capacitor coupled in series with the electrical current return conductor. In a variation of the disclosed system, the connections to the structural portion of the vehicle are made to the body and/or chassis of the vehicle. Systems built to according to the present invention have been demonstrated to have very advantageous properties. Electrical noise induced in several sensitive portions of the electrical system, both through magnetic coupling and through electrical conduction, are reduced. Also, radio performance is enhanced.
