Mounting block VAZ 2109 Electrician circuit includes all relays and fuses that are responsible for the power supply of nodes.
It combines the power lines and here all the elements of the current distribution schemes are mounted. The block represents a detachable box, on the inner sides of the caps of which are installed relays, fuses and fees with the conclusions of the wiring harnesses.
It should be borne in mind that the ECU of injection engines has a separate wiring.
Basic information on the mounting block
Depending on the year of the release and type of engine, the wiring circuit of the WAZ 2109 is assembled in various versions.
Thus, on the carburetor models, the block layout is presented in modifications of type 17.3722. It has round fuses in its composition, which often fail and require replacement.
In models with an injection engine, a new equipment for the VAZ 709 electric power unit was applied. Now the block has become more reliable due to the installation of new flat type fuses. Due to their knife design, a flat surface creates a large area of \u200b\u200bcontact, and they have become more reliable.
Find in the catalog The new unit can be marked 2114-3722010-60.
The difference between the VAZ 2109 of the electrical strokes of these two blocks:
- in connecting the radiator cooling fan;
- labeling relay connector and fuses;
- the absence of two relays.
Marking connectors and fuses
Due to the fact that there is a difference in the marking of the components of the arrangement scheme of nodes, it is necessary to know exactly what the Montage Electroscham VAZ 2109 is applied on equipment.
- year of release of VAZ 2109;
- engine's type;
- type of instrument panel;
- option configuration.
Knowing these source data can be found photo schemes on the site of motorists. It is possible to work in the same way with an interactive scheme that is displayed precisely the search for the electrical wiring.
On these schemes and indicates the labeling of nodes for each type of blocks. So, if the switching relays on the old scheme was designated in a numeral 1, then in the new block it is K1. All nodes are indicated on the schemes and the specification attached to them. All fuses are indicated on the block of the block. According to the scheme, the zone of the responsibility of each product is determined. Car VAZ 2109 Electroschem, the mounting unit of which includes the plugs of the connections of the wires, these products are marked with the letter sh.
How not to confuse wires
Many multi-colored wires should not cause difficulties in troubleshooting with their own hands. Wires have a clear focus on color:
- yellow - dimensions;
- red - stop signal;
- blue - reverse;
- orange-black - fog.
It remains only to choose the desired color of the wire and check its serviceability and connect.
Trouble-shooting
The electrical circuit of the mounting unit is the main node that ensures the performance of the car. If there is no needed skill, work on setting up the block is better to trust the specialists. The price of repair will be incommensurable with the cost of transporting the car failed in the path. If the repair is made independently, the instruction on the repair can be found on the video of the masters' training programs.
Dismantling block
To remove, remove the unit from the installation site, it is necessary to understand that it is an energy complex node. Therefore, disconnecting the wiring, it is necessary to marking connectors for subsequent collection.
Opening the hood, detect from the left side under the edge of the windshield, a block that is fastened with plastic clamps. They need to take and free the box. From above, it is covered with a rubber cover that shifts to the side. After moving the case, you should disconnect the block with wires.
After that, the block is released from the fastening two nuts and is lifted above the installation site, as far as the wires pull to it. When disconnecting the wires, melted the connectors to make it easier to spend later the inverse installation operation.
Shot block Install on the working surface and unscrew the fastening of the bottom cover consisting of 8 bolts. After that, insert the bug into the gap and perform the housing connector. The whole scheme will be before your eyes. Examine, compare with the instructions presented in the instructions and find a fault location. Often at the troubleshooting stage requires the help of a specialist.
It should be found:
- violation in the board;
- faulty fuse;
- related relay.
After replacing the part, damage corrections, the block is collected and installed in the place in the reverse order. Regardless of the type of electrical circuit used in the car, the blocks are set equally.
Characteristic block malfunctions
Often the failure occurs due to the blocked fuse. Find it easy. A replacement will be replaced by the same fuse with the same current load parameters. It is necessary to find out the reason that led to the triggering of protection. If the problem is not eliminated may happen a serious breakdown.
If the problem arose in the board, then it can be associated with the oxidation of the metal in the diagram. If the contacts oxidized, they can be cleaned. It should be removed the fuses and relays from the installation site. Work on cleaning current should be made carefully, and when using a soldering iron to restore the site, all measures are taken to protect the board against accidental damage. Replace the block will be much easier.
How to work with an electroblock scheme
Using the input data of the VAZ output in the information bases, you should find the circuit of the mounting unit of the type that is installed on a specific type of car. At the same time, two schemes are usually provided. The general view of the whole block makes it possible to estimate the complete similarity of the desired scheme with an existing node.
The second scheme is a wiring inside the block. It is required for detailed learning and troubleshooting. It is possible on the site to familiarize yourself with the interactive scheme, which will help track the diagram on the items.
