Badly connected battery cables may prevent a car from starting. The battery cables are the first and last components in every electrical circuit in a vehicle, with power leaving the battery along one cable and returning along the other. Bad connections cause a loss of voltage, increased current and poor performance. Really bad connections completely prevent the flow of electricity causing all the electrical systems to cease working. Fixing bad connections on a battery cable is a straightforward task.
