,## What is a fuse and what types can you find for your 124?,,In short:The fuses are the elements thatprotect the electrical circuits. They are cheap, disposable and there aredifferent typesaccording to their usage and the amount ofamperagethey transmit.There are Bosch fuses (or torpedo or GCB), cylinder fuses (or cartridge) made of glass, blade (or spade) fuses, cartridge fuses (JSCASE and MCASE), and high current fuses. The same car may have up to 3 types of fuses for its different circuits.,Fuses are pieces thatprotect the electrical circuits. That is to say, every time an electrical component of your 124suddenly stops working, there might be ablown fuse. The good news is that fuses are reallycheap and easy to replace. For this reason, before you mourn the loss of your stereo, air conditioner, or other devices, you should first check these little pieces.,All of them work in the same way and, the other good news is that they have no front or backside, so they areeasy to put into place. Despite their small size, they have acalibrated conductor for the highest current they can withstand, and if the current goes over this value, the conductor breaks, which interrupts the circuit and makes it impossible for the current to keep on flowing. The visible result is that the system stops working, but it is just because there is no current, not because of a serious problem.,Each type of fuse has anormalized valuethat can be easily recognizable because it isengraved in its body.,You can see where the fuse box of your 124 is located and what each fuse protects in theowner’s manual.,⚠️Every time you change a fuse, you should do it while your 124 is turned off.,,## Fuse types,,There are many fuse types, but these are the most common in the automotive industry:,Blade (or spade) fuses:,They are used in vehicles manufactured since the year 2000 up to now.,They have a rectangular shape, a flat contour, and a plastic, transparent body.,There are many different sizes:Micro2 (APT – ATR) – with 5 to 30 amperes.Micro3 (ATL) – with 5 to 15 amperes.Low profile Mini (APS), wrongly known as “”micro”” – with 2 to 30 amperes.Mini (ATM – APM) – their ends are smaller than those of Micro2 fuses – with 2 to 30 amperes.High/Regular/Standard – with 0.5 to 40 amperes.Maxi (APX) – with 20 to 120 amperes.,Cartridge fuses (JCASE and MCASE):,They usually have a female connector, but there are also male ones. They can withstand currents between 20 and 60 A. They have different sizes; the most common ones are MCASE and JCASE. The latter can be of standard size or low-profile (LP).,High current fuses:,They are used for high currents. They are usually present incharging and ignition circuits.They can be found close to the battery.They may have a plastic cover or not (bare fuses). They can withstand up to 500A. You can find them in two sizes; MIDI® fuses are tightened with 5mm bolts, while MEGA® fuses are tightened with 8mm bolts.,Since they are metallic, they are more resistant than t
