Note: The list of electrical equipment installed on the vehicle is determined by the configuration of a particular model. If necessary, refer to the Owner's Manual or to the supply department of the original Opel service station.
Attention: Before you start servicing the components of the onboard electrical equipment, read the requirements of the safety regulations for working with electrical appliances.
The vehicle is equipped with a 12-volt negative ground electrical system. The power supply to lighting fixtures and other consumers is carried out from a lead-acid type battery, which is recharged from an alternator. All components are interconnected by wires, most of the contact connectors of the onboard electrical equipment circuits are made of plastic and are multi-pin. The reliability of the articulation of the halves of such connectors is ensured by snapping the locking tabs of the latches mounted in the plugs. Before disconnecting such a connector, first carefully study its design - it is often not at all easy to determine how to fix its halves by eye; some connectors are equipped with multiple locking assemblies. To avoid accidental damage to the contact terminals mounted in the connector, when disconnecting the connector, pull only on the plug and in no case on the wiring harness.
This Chapter describes the procedures for repair and maintenance of electrical components installed on the vehicle and not directly related to the operation of the engine. For maintenance information on components such as the battery, alternator and starter, refer to chapter 5, dedicated to engine electrical systems.
To avoid electric shock or fire as a result of an accidental short circuit, disconnect the cable from the negative terminal of the battery, and in some cases completely disconnect the battery - be sure to follow the recommendations given in chapter 5. Regularly check the condition of the wiring harnesses and the reliability of their fastening in intermediate clamps, clamps and strappings. Make sure that the wire insulation does not fray when in contact with components located adjacent to the harness.
