Checking and replacing fuses
As you know, fuses protect against overloading the electrical system of our cars. When a component stops working, it is most likely that a circuit breaker has tripped or a fuse has blown. Therefore, the fuse responsible for the component should be checked before repair. A blown fuse will be indicated by a melted or completely ruptured tape inside the fuse.
Remember this before replacing the fuse!
- remove the ignition key
- check that everything has been switched off
- always replace fuses with the same amperage.
