Toyota RAV4>> Electric equipment>> Replacement of wires of the rechargeable battery
Periodically examine on all length of a wire, connected to the rechargeable battery, on absence of damage, the damaged and burned through isolation and corrosion. The unreliable connection of wires increasing contact resistance will reduce the size of the current consumed by a starter and it will create difficulties at launch of the engine.
Check clips on the ends of wires for lack of corrosion. Presence of white flakes under isolation demonstrates that the wire was affected by corrosion and it needs to be replaced. Check clips for lack of the deformation reducing a spot of contact with the plug of the rechargeable battery.
You make replacement of wires of the rechargeable battery as follows:
At first disconnect a wire from the negative plug of the rechargeable battery, take it aside and isolate for an exception of casual connection to the rechargeable battery.

       PREVENTION
Even if it is necessary to replace only the wire connected to the positive plug first of all disconnect a wire from the negative plug of the rechargeable battery.

After a detachment of wires from the rechargeable battery, disconnect them from the opposite sides.

Fig. 15.1. The place of connection of a "mass" wire to a car body


Disconnect wires from the traction relay of a starter, the block of safety locks and "mass" wires from a body and the power unit (fig. 15.1) .
Note an arrangement of each wire to guarantee the correct installation of a new wire.
When replacing wires use new wires with the same sections and length as replaced. Positive wires of usually red color also have the bigger section (diameter), and negative — black color and their section is less, than positive wires.
Wire brush clear carving contact of the traction relay of a starter. For protection against corrosion apply a thin film of technical vaseline on plugs of the rechargeable battery.
Fix on new wires clips for connection to plugs of the rechargeable battery and fix them by a bolt and a nut, having tightened them it is very reliable.
Before connection of a new wire to the rechargeable battery be convinced that the wire will not be tense.
After installation of new wires connect a wire of "weight" to the negative plug of the accumulator.
