The battery cables and battery cable ends carry power to all of a vehicle's electrical components. They must be tightly secured and free from corrosion in order to work properly. A battery cable replacement is needed when the battery cables have stopped carrying power to the vehicle's electrical components.
When replacing the battery cable or the battery cable ends, the emergency brake should be applied, the keys removed from the ignition, and all electrical components should be switched off. After replacing the battery cable or cable end, the time clock and radio presets should be reset.
While most manufacturer factory warranties and extended auto warranties do not cover a battery cable replacement, there are maintenance plans available that will cover the cost of a battery cable inspection. By having the battery cable inspection, it could prevent vehicle breakdowns.
