On the models of cars under consideration, most of the fuses (and relays) are located in the mounting block, located on the left under the instrument panel. The procedure for removing the mounting block is described in Chapter Body.
The second fuse/relay mounting block is located in the engine compartment of the vehicle, has a separate design and is equipped with removable covers
Each individual fuse is used to protect a specific electrical circuit or several circuits at once. An identification card with a diagram of the location of the fuses in the mounting block is usually glued to the cover of the latter, on its inner side.
Fuses of compact design, equipped with bayonet contacts, are used in the fuse boxes and, if necessary, can be easily removed from their sockets in the box with your fingers. If any of the power consumers fails, the condition of the corresponding fuse should always be checked first. Turn the key in the ignition switch to position II and use a test lamp to probe the open terminals of each fuse. If the lamp lights up when connected to each terminal, the fuse is OK. If voltage is present only on the power supply side, the fuse has blown. Note also that the fuse body is usually made of transparent plastic, through which the condition of the working jumper can be easily determined.
The fact that the fuse contact jumper has burned out is easily detected by visual inspection of the element, which has a translucent body
When replacing a blown fuse, make sure that the replacement element you prepare matches the type of the one that failed. Fuses designed for different nominal current strengths may not physically differ from each other, but they are not interchangeable. Each electrical circuit has different operating parameters and requires different degrees of protection, so replacing a fuse designed for a certain current strength with one that does not match its parameters is fraught with the most serious consequences (until a fire breaks out). Operating parameters of the fuse (rated current) are usually marked on its plastic body, in addition, color identification is additionally used (see Specifications in Chapter On-board electrical equipment).
A special clamp can be attached to the inside of the fuse box cover, the use of which can significantly simplify the procedure for removing the fuse.
A special fuse extractor clip is usually attached to the inside of the fuse box cover
If the new fuse also fails immediately after installation, there is no point in replacing it further - first you should identify and eliminate the cause of the overload in the circuit. In most cases, this is a short circuit in the connecting wiring caused by damage to its insulation. Spare fuses are usually placed in free terminal blocks of the mounting block.
All models of the vehicles covered by this Manual are provided with additional protection for the electrical equipment by up to eight main fuses, housed in a separate, lidded unit mounted on the wall of the mounting block located in the engine compartment. Blowing out any of the main fuses will de-energize most of the electrical equipment. Always disconnect the battery before replacing the main fuses. Replacement main fuses are always available from the supply department of your Opel service station.
If your car stereo is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery! Remember that a blown main fuse must be replaced with a replacement fuse of the same amperage.
