We check the alternator fuse if the battery of our car is discharged.

Model: Hyundai Sonata NF, MK 5 - Years 2005-2010
Part: Fuse box

In this video, we see how to behave if the battery of our car suddenly runs out, or if the battery light comes on. The car in the video is a 2008 Hyundai Sonata, but the concept is generally applicable to all cars. The reason is almost certainly a malfunctioning alternator, but before replacing it, it is worth trying to check the relevant fuse. So let's check the owner's manual - or one of our tutorials - to see which fuse is related to the alternator, and test it with a voltmeter or a multimeter (which will work fine). The fuse is not the problem in this case, so the issue is likely with the alternator or the wiring.
