The basics of any electrical circuit is to have electric current complete a round trip from +VE to -VE of the power source; in this case, the car battery or the alternator +VE point and the -VE are usually grounded to the car body.
Sometimes, the connections are not conducting well especially when aged and contact points get corroded. Additional grounding cables are needed to help improve electrical performance in the car.
This article will measure the resistance value of a NEW car and the results after grounding. Continue reading “Grounding : Fundamental” »
