Battery Cable End Replacement

The battery cables and battery cable ends carry power to all the car's electrical components (starter motor, lights, stereo, etc.).

The battery cables must be secure and free from corrosion to function properly.

If battery cables are not properly secured, or if they suffer from corrosion, the vehicle may be hard to start, or may not start at all.

When replacing the battery cable or the battery cable end, apply the emergency brake, remove keys from the ignition, and turn off all electrical components. After replacing the battery cable or cable end, you'll need to reset the time clock and radio presets.

The battery cable terminals must be kept clean and free of corrosion. If they become dirty or corroded, they will rob the vehicle of needed electrical current.

When replacing any battery terminal the cable itself must be inspected, if there is any evidence of corrosion in the cable strands the entire cable must be replaced. This is because the corrosion inside the cable will absorb critical amounts of electrical energy. This excess absorption of electrical energy in the cable can get to the point where the vehicle's starter will not turn over the engine even though the battery and starter are brand new. Corroded cables can absorb well over 50% of the electrical energy, making the actual voltage available from the battery 6 volts or less!
