Most often, during the daily operation of the car, electrical equipment malfunctions occur. For objective reasons, the repair of electrical equipment should preferably be carried out by qualified car service specialists.
WARNING
An electrical failure (short circuit) can lead to a fire in the wiring and even a fire. If any electrical circuit fails, first check to see if the fuse protecting it has blown. Replace defective fuse. The repeated blowing of the same fuse serves as a signal for the immediate repair of the corresponding electrical circuit .
WARNING
It is strictly forbidden to replace a blown fuse with another, larger "value" or "bug". To facilitate troubleshooting, use the wiring diagrams at the end of the book.
