Check of a condition and replacement of wires of the battery
|
|
The negative wire always should be disconnected first of all and be connected in last! |
Regularly examine battery wires on all their length on presence of signs of mechanical damages, cracks and прогаров isolation, and also corrosion traces. Do not forget that infringement of quality of electric connection of contact plugs is capable to lead to difficulties at engine start, and also to decrease in efficiency of its return.

Check up клеммные clips of wires on presence of cracks, signs of loss of copper veins and corrosion traces. Presence accumulated under the insulation layer close клеммных tips white порошкообразных adjournment speaks about development of corrosion and necessity of replacement of a wire. Check up plugs of the battery and fastening clips on them of tips of wires on presence of signs of deformation, easing of bolts and corrosion traces. |
The negative wire is always disconnected from the battery first of all and connected in last. Do not forget to disconnect a negative wire even in the event that only one positive is subject to replacement.

|
If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for equipment introduction in action! |

- Disconnect from the battery old wires (at first negative), then "walk" on each of them to the opposite end disconnect from the traction relay of a starter (positive) and plugs grounding (negative). Try to remember routes of a lining of both wires for the purpose of their observance at installation of the new.
- Take a wire subject to replacement with itself in shop as the sample. Extremely important factor is conformity of a design of clips of a wire to the form of connecting plugs on the car.

|
Wires are easy for distinguishing from each other on colour of isolation, always black at negative and red at the positive. Besides, the positive wire usually has большее section. |
- Wire brush smooth out a carving on connecting plugs of the traction relay and grounding. After removal of all traces of corrosion slightly grease carving coils бескислотным with vaseline for the purpose of prevention of development of corrosion further.
- Connect a wire to the plug of the traction relay / of weight and strongly tighten a fixing nut / a bolt.
- Before to connect a new wire to the battery plug make sure that it freely reaches it without an excessive tension. Carefully smooth out polar plugs of the battery, then slightly grease them бескислотным with vaseline.

First of all always connect to the battery a positive wire, then negative.
