7.5. Accumulator wires - check and replacement

Periodically examine wires on existence of damages, cracks, a rupture of isolation or corrosion. Check a condition of contacts and clear them of corrosion. Always disconnect a wire of the minus plug the first and connect his last.
The battery - removal and the Removal installation
1. Disconnect both cables from the battery, having begun with a cable of a negative pole.
2. Disconnect a fastening collar.
3. Lift the battery. Consider that the battery heavy.
4. Having got the battery examine a tray, believe corrosion existence.
5. When replacing the battery be convinced that parameters of the new battery (dimensions, the capacity and current of return) just the same, as at replaced.
Installation
6. The battery is installed upside-down.
4. Power cables - check and replacement.
Check
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 be a cause of failures at launch of the engine, and also deterioration in 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 the white shelled raid under isolation in the place of the plug demonstrates 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.
3. At removal of cables always disconnect the battery from weight first of all, and connect to weight at the latest moment, in order to avoid a zakorachivaniye of poles of the battery the tool which plugs drag on. If it is necessary to replace only a cable of a positive pole, then at first disconnect a cable from a negative pole (the procedure of removal of cables is in detail described in Chapter 1).
Replacement
4. Disconnect old cables from the battery, 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 along which the cable is laid to lay a new cable to the place of being in operation.
5. If cables are replaced new, then getting new cables, take with yourself old. It is extremely important that new cables in accuracy corresponded to old. It is easy to distinguish a cable of a positive pole from a cable negative, - isolation of a cable of a positive pole of usually red color, these cables have bigger cross section, the accumulator plug differs in big diameter. Isolation of a cable of connection with the mass of black color, cross section and diameter of the plug is less, than at a cable of a positive pole of the battery.
6. Clear carvings of fastening of cables of the battery on the traction relay of a starter and on a body, remove corrosion traces.
Instruction
For protection from corrosion grease carvings with technical vaseline or special protective structure for accumulator plugs.
7. Attach a cable to the traction relay of a starter or to weight, reliably tighten nuts and bolts of fastening.
8. Before accession to the battery of a new cable, be convinced that the cable has sufficient length, and it will be established without tension.
9. At first attach a cable to a positive pole of the battery, then to negative.
