Battery Cable Replacement
How are battery cable issues diagnosed?
We have all heard of the term “dead battery”, or experienced this issue ourselves, but it is important to note that a “dead battery” does not necessarily mean the battery is at fault. Vehicles exhibiting the symptoms noted above will be connected to a starting and charging system test machine. This is an advanced device that allows automatic testing of every part of the starting and charging system by following onscreen instructions. The machine will display results, and indicate the possibility of battery cable failure, but may also require the servicing technician to complete visual inspections while testing is in progress. If the battery is found to be discharged below the required voltage, it will be recharged, retested, and possibly replaced before diagnostic work continues.
How is a battery cable replaced?
Battery replacement for most vehicles is typically fast and easy. The battery cables should be removed, any battery insulation material will be removed, and the battery retaining bracket will be loosened or removed. The battery will then be free to removed. The new battery will be installed in the reverse order of operations. Note that some vehicles place the battery in the trunk, the front or rear wheel well, or under the seats. In these instances, accessibility of the battery may dictate dismantling several components before replacement can being.
RepairPal Recommendations for battery cable issues
We recommend using battery cables rated identically, or larger than the original battery cables. Using too small of a battery cable will result in undercharging the battery, extremely high temperatures in the battery cables, fire hazard, and repeated failure.
