Battery cables transfer the current from the battery to other electrical devices (starter, alternator, fuse block). Without battery cables, there will be no electrical power in any part of your car. The cables are positioned under the hood and are joined to the battery on one end and the engine and electrical accessories on the other. All cars have multiple cables. These cables can become corroded and cause bad connections, which will not allow the right amount of current to be transferred to the electrical components in the car.
Facts to Note:
Usually, battery cables cannot be mended and must be changed as an assembly. But in some cases, your mechanic may be able to cut the corroded portion of the cable and install a terminal end. By doing this, you can dodge changing the cable assembly.
How to Fix:
Carry out a voltage drop test.
Take away and change cables if voltage drop is more than 0.1 volt.
Check charging system.
Carry out a starter draw test.
Test for proper voltage output from alternator.
Corrosion is the battery cable’s worst enemy. If you open the hood of your car, you may find a white or bluish powdery substance (dried acid) on the battery and cables. This acidic material will corrode the battery terminal ends and the battery cable. It is a good practice to have the battery and cables checked and cleaned at consistent intervals (we recommend every other oil change). This will stop the corrosion from building up and it will prolong the life of the battery cables.
Common symptoms indicating you may need to change the Battery Cable:
Car does not start.
Clicking noise when starting the car.
Electrical components (e.g. lights, radio, horn) may not work.
Importance of this service:
Battery cables transfer current from the battery to the electrical mechanisms of the vehicle. Without working battery cables, the battery has no way of outputting energy. The alternator and starter rely on battery cables for power, so faulty cables mean that your vehicle won’t start up or have any electrical energy.
