Periodically inspect the entire length of each battery cable for damage, such as cracked or burned insulation and corrosion. Check the cable-to-terminal connections at the ends of the cables for cracks, loose wire strands, and corrosion. Look for white, fluffy deposits under the insulation at the cable terminal connection, as this indicates corrosion and the need for replacement. Also, check the terminals for distortion, missing mounting bolts, and corrosion. When replacing the cables, always disconnect the negative cable first and hook it up last to avoid shorting the battery. Even if only the positive cable is being replaced, disconnect the negative cable from the battery first. Disconnect and remove the cable, ensuring that the replacement cable is the same length and diameter. Clean the threads of the relay or ground connection with a wire brush to remove rust and corrosion, and apply a light coat of petroleum jelly to prevent future corrosion. Attach the cable to the relay or ground connection and tighten the mounting nut/bolt securely. Before connecting the new cable to the battery, make sure it reaches the battery post without needing to be stretched. Thoroughly clean the battery posts and apply a light coat of petroleum jelly to prevent corrosion. Finally, connect the positive cable first, followed by the negative cable.
