13.24.3.3. Detection of bad grounding
THE GENERAL DATA

The negative plug of the accumulator is connected to "weight" – to metal of a body, the engine or a transmission. Thus many elements of an electric equipment are connected in such a manner that the positive wire, thus a current approaches to them only comes back to the accumulator through body metal. It means that fastening of an element of an electric equipment and a body are a part of an electric chain.

Thereof the bad or rusted fastening can cause refusal of work of an element or lead to its unstable or bad work. In particular, bulbs can burn with dim light (especially if in a point of grounding of this bulb grounding of any else included element of an electric equipment is carried out), electric motors can slowly work, and also work of one chain can influence imperceptible at first sight on work of other chain. Do not forget that on many cars grounding wires between some elements, such, as the engine / of transmission and a body, that is in those places where there is no direct contact between metal elements because of soft rubber fastenings or a paint coat are used.

PERFORMANCE ORDER
1. For check of reliability of grounding of an element it is necessary to disconnect the accumulator and to connect one of probeов an ohmmeter to reliably earthed element.
2. Connect another probe to a wire пли to connection with a body which is necessary for checking up.
3. Resistance shown by an ohmmeter should be equal to zero; if is not present, check up connection as follows.
4. If you assume absence of grounding, disassemble connection and clear a site of a body and the wire plug (or a surface of grounding of an element) to pure metal.
5. Carefully remove all traces of a dirt, then by means of a knife remove all paint so that reliable contact of two metal surfaces has turned out.
6. At assemblage reliably tighten socket fastening; at connection of the plug of a wire establish a washer with the jagged edges between the plug and a surface of a body for maintenance of reliable connection.
7. At connection prevent corrosion occurrence in the future, having put a layer of vaseline or silicone greasing.
