The alternation - the general information and check of usefulness of functioning General information
To give of the provision of power or a sign of the management of some consumers of the electric power in the car (like the component ones of the system of the injection of fuel, a horn, an author, the supporter of system of cooling, lights of thick fog and other) the alternations are in use. In fact the alternation represents the electric key that supplies short circuit in / in an outline in a sign of low tension. In case of an alternation exit out of the operation there is a refusal of the functioning of the corresponding consumer. The sieges of installation of blocks of meeting of the alternation and locks of security the illustrations specify the Agreement of Blocks of the Locks of Security and Alternation in a reason compartment. The description of the check of the usefulness of the functioning of the alternation happens down. The failed alternations are subject to the substitution.

- If it is not possible to discover a way of be lighting of the alternation in the corresponding electric outline according to the schemes of electric connections (The schematic diagrams of the electric connections), it is necessary to be remembered that the approximation of the check of any alternation in beginning is identic in all the cases.
- In most of the cases the outline of the management is always joined to two of captures of contact of the alternation. When the offer in these captures of the current of tension of low tension begins the circular in a bend of the management of the alternation, therefore, there is a short circuit of great contacts of an outline of work of the consumer of the electric power. Other captures are the captures of the official (in / in) an outline.
- For aims of the simplification of the identification of captures of the alternation the explicative marking with the image of the scheme of the connection of keys is applied normally in his case.
- Before the removal of the alternation they secure that the corresponding outline is cut of the power.
- Join the point of passage of equipped wire of a lock of security between one of captures of the management of the alternation and the positive capture of the battery. Through the second land of point of passage of wire the second capture of the management, – the alternation will publish the click. Some alternations demand the compulsory respect to the polarity of the connection, - if the click did not happen, try to modify the polarity of the connection of captures of the management.
- In the connected wires the passage points check the existence of the condutividade between the outline taken V/V, when joined an ohmmeter according to the key scheme in case of alternation.
- In the negative result of the check they substitute the alternation.
