Patent ID: 7301747

Claim:
A voltage stabilizing and surge preventing vehicle grounding system being laid in an engine chamber interconnecting a negative terminal of a vehicle generator, a gear shift controller, an engine cover, a battery unit, a starting motor, an antistick brake motor (ABS), a vehicle computer, a throttle valve, a dash board, a compressor, a relay assembly respectively to a grounding terminal of a chassis so as to form a closed loop wire; a device provided with the closed loop grounding wire including: a surge absorber having an accommodation cavity enclosed by a housing formed of two sections, an electrical circuit board contained inside has a positive and a negative conductor emerged out of the housing to form a circuit with a resistor, a fuse element, an indication lamp, and a plurality of capacitors; a surge suppresser having an accommodation cavity enclosed by an environmental protective heat resistive plastic housing filled with an insulated environmental protective material, and a plurality of successively arrayed annular magnetic hollow cores with an insulation electrical conductor wound around and passing through the channel formed by said hallow cores to extend out of two ends of the surge suppresser thereby forming a first and a second conductors; and a multi-tapped closed loop grounding wires provided with nine nodes thereon.
