Look at the readings and compare them. If you have different readings, you have a blown fuse that needs replacement. The same reading shows the fuse is okay.

Fuses - RS Components A Complete Guide to Fuses - RS Components

When specifying a fuse for an after-market application, the key consideration is that the fuse should be the weakest point (i.e. lowest rated component) so that it always blows before any damage occurs to other parts of the electrical circuit. However, you also do not want the fuse to keep blowing under normal operation (known as a nuisance blow), so the two elements to consider are: When a fuse blows, the electrical supply to a particular circuit is immediately cut off. This lowers the risk of fire and prevents damage to the wiring. The blown fuse can safely be replaced without the risk of electrocution. Are Old Fuse Boxes Illegal? Resettable SMD fuses, by contrast, can be used multiple times. They function in a similar way to resettable thermal fuses and are available in multiple sizes and capacities. Striker Fuses We will explain the different car fuse types further on in this guide, but the specific type of fuse your car needs will depend on a selection of factors. This includes the make and model of the vehicle, the existing fuse, and the electrical circuit or equipment it is designed to protect.The signs of a blown fuse are apparent regardless of the fuse amperage. So it is much easier to find out when you have a burnt fuse. Final Words The 5 amp fuse should always be a weak point between two components. Here’s why I said so; the metal strip across the fuse poles is there to transmit current from the first terminal to the next one. And the strip is designed to cut or blow out whenever there are arc issues or overloads on the system. If the fuse does not cut when any of these happens, the electrical issue will blow the electronics that the fuse is protecting. Once you have replaced any necessary powerpoint fuses, locate your fuse box, using your torch if necessary. Ensure that the master switch is in the off position. It should be following a trip, but you should always make sure that this is the case

Surface mount devices (SMDs) are electrical components that sit on the surface of printed circuit boards (PCBs). SMD fuses are available in both resettable and non-resettable forms.Obtain the tools you will need - typically fuse wire, wire cutters, a screwdriver and a torch so you can see what you are doing Strip and midi link fuses are for higher current or 'power' applications (e.g. winch motors) with mega link fuses used for very high current applications. These fuses are bolted down into fuse holders or boxes. AC fuses are specifically designed for use with alternating current circuits. They are more resistant to electric arcs when the fuse blows than DC fuses and more compatible with standard voltage power supplies. They can usually cope with higher voltages, too. DC Fuses If the visual inspection is inconclusive, use a multimeter to test whether the fuse is working or not Do you suspect you have a blown 5 amp fuse and are wondering what does a blown 5 amp fuse look like? Firstly, it’s crucial you understand what a fuse is and what it is used for in a car. A fuse is a two-terminal component with a tiny ribbon across the terminals to transmit electric flow from one terminal to the other.
