Since it is impossible to include in this manual the electrical diagrams of all models and years of production of cars that are described in this manual, the most typical diagrams that are most often referred to are given below.
Before you begin diagnosing any electrical circuit, check the fuses and circuit breakers (if installed), to make sure they are in good condition. Check the battery charge and that the battery cable connections are clean and secure.
When checking the wires, make sure that all connections and connectors are clean, without broken or poorly connected contacts. When disconnecting a connector, do not pull on the wires, only grasp the connector body.
