In this video, I show you an extremely simple test, but of extreme importance to solve various types of problems with your car! The test is performed using only a multimeter, and the objective is to check whether the car's grounding points are fully functional, or whether there is a bad connection in the extension of the negative battery cable, in the transfer to the body, engine or electronic injection. If there is a fault, the car's operation may be affected, causing idling oscillations, failures, difficulty starting, increased consumption, etc. Although it is performed on a Clio, the procedure is practically the same for all cars, whether Renault or not, but it will be necessary to identify the grounding points of each car.
