Each electrical device in the car is designed for a certain voltage. The diameter of the supply wire is calculated taking this voltage into account. If the current consumption in a certain circuit, for example, due to the connection of additional consumers, increases, then the supply cable experiences an additional load. It can overheat or even burn out if the current flow is not interrupted in a timely manner. This function is performed by fuses. To avoid complete blackout onboard network each circuit has its own fuse. However, the connections to the battery, alternator, starter and ignition switch are not fused.
To remove and replace fuses, use the plastic clip attached to the cover of the central distribution panel (see illustration 3.0).
If a new fuse blows immediately after installation, then make sure that the fuse of the correct rating was installed, and not less. If the rating matches, then check separately all consumers of this circuit. Please use the appropriate electric circuit. If necessary, disconnect all consumers of the circuit, and then connect one at a time. If the fuse blows when another consumer is connected, then this consumer is faulty.

In this section, we will consider the purpose of the fuses on the Audi 80 (B3) 1990-1992. release. Audi 80 debuted in 1972 and soon won the prestigious title of "Car of the Year". With modifications, the Audi 80 has been produced for more than 20 years, and is still considered one of the most reliable and prestigious cars. Until 1976, the Audi 80 B1 was produced, from 1978 to 1986. - Audi 80 B2, in 1986-1991 - Audi 80 B3, and the last three years (until 1994) - Audi 80 B4. The Audi 90 modification denoted Audi 80 cars of a higher configuration and with the most powerful motors. Most deep modernization The brand was produced in 1986. The Audi 80 received the only body type - a four-door sedan. The main innovation was the full galvanization of the entire body, which made it possible for Audi to give a ten-year warranty from through corrosion body series Audi 80 b3 and b4. In 1991, the last restyling was made. From model range Audi 90 disappeared - now all cars of this class bore the designation Audi 80 (in the USA the name Audi 90 remained). The wagon body appeared again - the Audi 80 Avant. Released in the same year diesel audi The 80 TDI is the world champion in efficiency. In 1994, the Audi 80 replaced the Audi A4 on the assembly line.
The failure of any electrical system may be caused by a blown fuse.
Fuses are assembled in one block. The fuse/relay box is located under the engine compartment hood. The fuses are covered.
There are four spare fuses on the fuse box different power. It's a good idea to have a set of spare fuses in your car. They can be purchased from an Audi dealer.
A- spare fuses
IN- additional fuses (numbers 23-28)
Fuse replacement
Before replacing a fuse, turn off all headlights, bulbs, and electrical equipment of the vehicle, and remove the key from the ignition in order not to damage the electrical system.
To remove the fuse/relay box cover, disengage both latches on the outside of the cover.
Review the fuse list to determine which fuse is protecting the failed circuit.
Remove the blown fuse with a plastic clip.
This clip is located on the cover of the fuse/relay box.
Replace the blown fuse, which can be identified by the blown metal strip, with a fuse of the same rating.
Note!
Don't use a fuse more power, as this may result in damage to any of the electrical equipment and a fire.
If the fuse constantly blows, do not replace it continuously.
Need to find the source of the overload or short circuit. In no case should a piece of foil or wire be installed instead of a fuse, as this can damage any of the electrical equipment and cause a fire.
Audi 80 The third generation has been produced since 1986 in a round, fully galvanized body for corrosion protection, with a soft wedge shape. The year of manufacture of the car is quite old, so the likelihood of problems with electrics or appliances is high.
In case of occurrence emergency situation associated with electrical appliances, you should first check the integrity of the fuses and relays Audi 80. This article will help you.
