Hello, I read the link below. Basically, the article is simply explaining the breakdown of the fuses and the functions of your fuses. The way they work is these kinds of fuses are used in all vehicles which allow lights to work, AC, Brakes, Power lock, Windshield wipers, essential everything. The graphs show the voltage put out and the cut off on the fuses. I hope this helps with understanding the usage of fuses. To help it may be helpful for you to go out and look in the fuse box in your car and look at the numbers on them which will help you relate with the fuses in your car. If you see any black dust on any of them it may need to be replaced. I am knowledgable about this due to my years of working on my old BMW.
