Check
PERFORMANCE ORDER |
1. Periodically check cables on all length, damage, cracking or a burn-out of isolation of cables, and also corrosion are not allowed. Unreliable connection of the battery can cause refusals at engine start-up, and also deteriorations of operational qualities of the engine. |
2. Check a condition of connections of poles with plugs, existence on them of corrosion, cracks and weakening of fastening of wires. Existence of a white being shelled raid under isolation in a place of the plug testifies to corrosion of conductors of a cable and need of its replacement. Check existence of corrosion and deformations on plugs and a condition of bolts of fastening. |

Replacement
PERFORMANCE ORDER |
1. Disconnect from the battery old cables, track laying of cables on their length and find places of their fastening to a starter and to weight, disconnect cables from the traction relay of a starter and weight. Remember a route of laying of a cable to lay a new cable to the place of the replaced. |
2. If cables are replaced new, getting new cables, grasp with itself old. New cables should correspond in accuracy to the replaced. The cable of a positive pole is easy for distinguishing from a cable negative – isolation of a cable of a positive pole of usually red color, these cables have bigger cross-section section, the storage plug differs in big diameter. Isolation of a cable of connection with mass of black color, cross-section section and diameter of the plug is less, than at a cable of a positive pole. |
3. Clear carvings of fastening of cables of the battery on the traction relay of a starter and on a body, remove corrosion traces. |
4. Attach a cable to the traction relay of a starter or to weight, reliably tighten nuts and fastening bolts. |
5. Before accession to the battery of a new cable be convinced that the cable has sufficient length, and will be established without a tension. |
