Question

DentroTest · Accepted Answer

Fuses are calibrated protection elements designed to safeguard the electrical system and the components of the vehicle against overloads and short circuits. When replacing a blown fuse, the new replacement must have the same amperage and meet the specifications indicated by the manufacturer. If a fuse with a higher amperage were fitted, the filament might not melt in time in the event of excess current, allowing a destructive current to pass that would burn the wiring or the associated electrical equipment, with the resulting risk of a serious breakdown or fire.
