Q: What Is the Role of Fuses, Circuit Breakers, and Fusible Links in Electrical Circuit Protection?
A: The vehicle's electrical circuits are covered by a mixture of fuses, circuit breakers and fusible links. The fuse block can be seen beneath the instrument panel on the left side of dashboard. Every one fuse covers a particular circuit and these circuits are indicated on the fuse itself. The miniature fuses are used in the fuse block with blade terminal design for fast removal and installation with fingers. Always check if the fuse has blown whenever an electrical component fails to work properly. A test light is the best method of checking fuses. You should see whether each fuse has power at its exposed terminal tips or not. When there is power on one side of the fuse but none on the other, it means that this device is blown out. This can also be visually observed when it happens to occur. Remember that broken fuses have to be replaced using correct types only. Fuses will physically fit into any rated slot; however, you must use only those which suit specific ratings accordingly! It's not recommended replacing a higher or lower value than specified fuse thereon! Each electrical circuit requires some amount of protection against overloads or short circuits caused by damaged wiring or components which fail due to age or accident.
