Pic. 13.2. Location of the fuse box under the instrument panel on the driver's side
Fuses and fusible links are used to protect electrical circuits. The fuse box is located under the instrument panel on the driver's side (pic. 13.2).
Each of the fuses protects its circuit, its belonging to a particular circuit is indicated on the cover of the fuse box.
Pic. 13.3. Using tweezers when replacing a fuse
The fuse box contains blade-type fuses, the color of which corresponds to the current strength of the fuse protection. In the event of failure of any element of electrical equipment, first of all, check the condition of the fuse. The health of the fuse is determined by the presence of a wire conductor connecting the contacts of the fuse. To replace a failed fuse, first turn off the corresponding electrical circuit and remove the fuse from the socket with tweezers (pic. 13.3).
Attention! Do not replace the fuse with a strip of metal or foil, as this may cause serious damage to the vehicle's electrical equipment.
If a newly installed fuse fails instantly when energized, check the circuit being protected. If the fuse protects several circuits, then they must be connected in turn in order to determine the faulty circuit by blowing the fuse.
The heater and air conditioner consume a lot of current, so the fuse box has a switch to protect their circuits. If the circuit is opened by the switch, turn off the heater and air conditioner before pressing the switch reset button.
Fusible links
In addition to fuses, electrical equipment circuits are protected by fusible jumpers. They are used in circuits that are not normally protected by fuses, such as the ignition switch circuit. The fuses used on these models consist of special wires that are installed in the fuse box located on the battery side of the fender of the car. Fusible jumpers cannot be repaired, they must be replaced with a wire of the same diameter (available from Mazda dealers). The replacement of fusible links is carried out as follows:
- eliminate the malfunction caused by the melting of the jumper;
- disconnect the wire from the negative terminal of the battery;
- remove the fusible link from the socket;
- Install a new fusible link in the socket.
