However, this usually occurs when you or your mechanic replaces a burnt fuse with a higher amp rating. How do you know if a 5 amp fuse is blown?

There are several types of fuse currently in use in the automotive market and the table below gives a brief description of each:The standard blade fuse (also known as APR, ATC or ATO fuses) is the most common with many cars now using the mini blade version (also known as APM or ATM fuses). Increasing in popularity is the micro blade version (also known as APS or ATT fuses) with more widespread use expected in the future as manufacturers attempt to fit more electrical systems into the same space

When searching for what does a blown 5 amp fuse looks like or how do you test a blown fuse, the first thing you should do is a visual inspection. Visual inspection means looking at the suspected fuse to see if it is blown. Fuses are critical in any electrical system and are used to protect a circuit's cabling from excessive current that could lead to damage and, very often, an electrical fire. Excessive current is most likely to be caused by three things: Micro3 – these are easily identifiable as they are the only type with three terminals instead of two The following diagram shows how electrical loads such as lights etc. might be fused in an after-market circuit. If replacing a blown fuse in a manufacturer-designed (factory) application, e.g. in a vehicle fuse panel, then the same type and rating of fuse should be used. If a fuse continues to blow then there must be a fault with the circuit and a higher rating fuse should never be fitted to overcome this, even temporarily. Doing this creates a high risk of component failure and electrical fire.There are some instances where fuses are not normally used and one example is for the, normally short, length of cable from the battery to the starter motor. Starter motors are normally the highest current draw electrical item on a vehicle as they have to crank the engine, and the current can reach several hundred Amps, especially with large diesel engines that have a high compression ratio. For this reason it is usually deemed impractical to fuse this length of cable, although some vehicles do have fusible links which are simply a small section of lower current rating cable encased in a fireproof sleeve. They are installed with the cable being protected and are designed to melt and break the circuit in an over-current condition. The other reason for not fusing the starter circuit is that if the battery is disconnected from the alternator whilst it is turning (as would be the case if a fuse blew) the diodes in the alternator's rectifier can be damaged. Mini - these feature the same body design as low-profile mini fuses but the key difference is that the terminals are much longer than with the low-profile mini 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: Connect the probes to the fuse terminals and note the reading. If there’s no reading on the multimeter, turn on the ignition or start the engine, as the case may be. Some fuses will not respond until you turn on the ignition or turn on the engine. As explained above, the first steps to replacing a car fuse are to locate the fuse box and the blown fuse and buy a new fuse of the same type, size, and current rating. Once you have the new fuse, you will need to carefully insert it into position within the fuse box or housing. Make sure to insert it into the correct location where the blown fuse was situated.
