Small fuse, big problem
Electrical system malfunctions are difficult for the average driver to fix. Fortunately, in most cases they are easily removed.
But as it turns out, it's not always that simple. .
In the event of problems with the electrical system, it is sometimes sufficient to replace a faulty fuse. The fuse plays a very important role in an electrical circuit as it protects the system from damage. In the event of a short circuit in the circuit, the fuse blows and the power supply is interrupted. If such a malfunction occurs in 
important systems, such as lighting circuits, fuel pump power, radiator fan power, cannot continue driving. But you should not panic, because even an inexperienced driver can fix such a serious malfunction. In most cases, the repair comes down to replacing the fuse. And here the first problem may appear, because it is not always known where the fuses are located. If we manage to find them, it will turn out that there are a lot of them and it is almost impossible to find the right one.
As a rule, fuse boxes are located under the dashboard and in the engine compartment. In most cars, individual circuits are described by a corresponding figure, so finding the right fuse is not difficult. The user manual and flashlight will also be very useful and should always be carried in the car. When you manage to find a damaged fuse, another problem may arise - there is no spare. But you can solve this problem on an ad hoc basis. Replace the fuse on a different, less important circuit. This can be, for example, a control system for power windows, radio, rear window heating or interior lighting. We will replace the missing fuses after we get to the nearest gas station (the quality of the fuses is comparable, so it doesn't matter where we buy them). When deciding on such a step, make sure that removing the fuse will not disable additional devices (such as brake lights) that have a decisive influence on traffic safety. When replacing a fuse, pay attention to its color, as the color indicates the current that can flow through the fuse (red - 10A, yellow - 20A, blue - 15A, green - 30A, white - 25A, brown - 7,5A). A, orange - 5A). Do not install a larger fuse, let alone bypass the circuit, as a blown fuse can indicate a serious problem with the system. Adopting a stronger one can even lead to a fire in the installation.
However, if replacing the fuse does not help (the new one will also burn out), unfortunately, you will have to use the help of an electrician.
