Check of a condition and replacement of wires of the battery

Periodically check battery wires on all their length on existence of damages, cracks and прогаров isolation, and also signs of corrosion of a vein. Bad contact of tips of wires of the battery can be at the bottom of difficulties at start of the engine and decrease in capacity developed by it.


  1. Check a condition of tips of wires put on plugs on existence of cracks, weakening of fastening on a vein and corrosion traces. Presence of a fragile korkoobrazny raid of white color on battery plugs, tips of wires and under isolation is a sign of corrosion of a wire in case of which detection it should be replaced. Check plugs and tips of wires on existence of deformations, losses or weakening of fixing bolts and corrosion traces.
  2. At removal of wires always first of all disconnect from the battery negative (and connect the last), the probability of a casual zakorachivaniye of a positive pole on weight by a key otherwise is not excluded at a weakening/tightening of a terminal clip. Even if only positive wire is subject to replacement before starting its removal disconnect from the battery negative (more detailed information on replacement of wires of the battery see in Head of Control and routine maintenance).

If the radio tape recorder in your car is equipped with a security code before disconnecting from the battery a negative wire make sure that this code know.

  1. Disconnect old wires from the battery, then track each of them till the opposite end disconnect from plugs of the traction relay of a starter and grounding. Try to remember how each of wires is laid in an impellent compartment for the purpose of their correct installation at assembly.
  2. In case of need replacements any of wires (or both) take with itself in shop the old. It is extremely important, that a new wire on a design of tips, to a standard size and other parameters corresponded to the removed. Wires have the distinctive features facilitating their correct identification at a choice: the positive wire is usually covered with isolation of red color and has bigger cross-section section; the wire of grounding of usually black color, also has the smaller size cross-section section.
  3. Remove from a carving part of terminal connections of the traction relay and weight of the engine corrosion traces by means of a wire brush. Slightly grease battery plugs with inhibitor of corrosion or acid-free vaseline for corrosion prevention in the future.
  4. Connect a wire to the plug of the traction relay or grounding and reliably tighten fixing a bolt/nut.
  5. Before connecting a wire to the battery make sure that it reaches it without a tension.
  6. The first connect a positive wire, afterwards - negative.
