The electrical circuits of the vehicle are protected by fuses and circuit breakers and fusible links, The fuse blocks are located at two places, one under the instrument panel and second in the engine compartment where the engine compartment fuse and relay box is located on the left side. On the under side of the cover there is a label which reads 'fusible link area' where there are cartridge-style fusible links and another fuse box is located inside the car at the left extremity of the dash behind a modest door marked 'fuse'. The fuse is designed for guarding a particular circuit, labeled on the cover of the fuse panel; miniaturized fuses with blades terminals allow quick swapping. When an electrical component ceases to function, it is imperative that the fuse be checked most times, using a test light to determine whether there is power at the exposed end of the fuse terminal; if the light turns on on one side but not the other, the fuse is blown; this is also further proved by visible examination as the element which joins the two terminals burns out. Blown fuses must be replaced by exact fuses, fuses that may look like the correct one, must not be used because each may provide the proper protection as stated by the amperage value molded in the fuse body. If the replacement fuse causes the circuit again to 'trip' upon switch on, then the faulty fuse should not be replaced back until the problem causing the initial tripping is usually a short circuit resulting from a poor connection or a faulty wire. Moreover, some circuits contain fusible links and are used in the circuits not generally fused, for example, high current side of charging or starting circuits. Inline fusible links are easy to distinguish by a thicker part in the cable; they are used, for instance, in the starter cable There are new cartridge types of fusible links that look like large fusinate cartridges and are located in the fuse and relay box within the engine compartment. To replace a fusible link, you want to pull the clamp off of the negative terminal of the battery, take the bad fusible link out and put in a new one of the same amps.
