Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation, and corrosion. Poor battery cable connections can cause starting problems and decreased engine performance. Also, inspect the cable-to-terminal connections at the ends of the cables for cracks, loose wire strands, and corrosion. The presence of white, fluffy deposits under the insulation at the cable terminal connection is a sign of corrosion and indicates the need for replacement. Check the terminals for distortion, missing mounting bolts, and corrosion. When removing the cables, always disconnect the negative cable first and hook it up last to avoid accidentally shorting the battery. Even if only the positive cable is being replaced, disconnect the negative cable from the battery first. Disconnect the old cables from the battery and trace each of them to their opposite ends, detaching them from the starter solenoid and ground terminals. Note the routing of each cable for correct installation. If replacing the cables, take the old ones with you when buying new ones to ensure identical replacements. Positive cables are usually red and larger in cross-section, while ground cables are usually black and smaller. Clean the threads of the solenoid or ground connection with a wire brush to remove rust and corrosion, and apply a light coat of battery terminal corrosion inhibitor or petroleum jelly to prevent future corrosion. Attach the cable to the solenoid or ground connection and tighten the mounting nut/bolt securely. Before connecting a new cable to the battery, ensure it reaches the battery post without needing to be stretched. Connect the positive cable first, followed by the negative cable.
