1. Periodically check the cables along the entire length, damage, cracking or burning of the cable insulation, as well as corrosion are not allowed. A poor battery connection can cause engine start failures and engine performance degradation.
2. Check the condition of the connections of the poles with the terminals, the presence of corrosion, cracks and loosening of the wires. The presence of white flaky deposits under the insulation at the terminal point indicates corrosion of the cable conductors and the need to replace it.
3. Check the presence of corrosion and deformation on the terminals and the condition of the fastening bolts.
4. Disconnect the old cables from the battery, track the laying of the cables along their length and find the places where they are attached to the starter and to the ground, disconnect the cables from the starter and ground traction relay. Remember the route along which the cable is laid in order to lay the new cable in place of the replaced one. Make sure that the cable is not under tension after installation.
5. If the cables will be replaced with new ones, when purchasing new cables, take the old ones with you. It is extremely important that the new cables exactly match the old ones.
6. Clean the threads of the battery cables on the starter traction relay and on the body, remove any signs of corrosion.
