Inspect the entire length of each battery cable periodically for damage, cracked or burned insulation and corrosion as poor battery connections can cause starting problems and decreased engine performance. Check the cable-to-terminal connections at the ends of the cables for cracks, loose wire strands and corrosion. White, fluffy deposits under the insulation at the cable terminal connection indicate corrosion and the need for replacement. Also, 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 shorting the battery. Disconnect the old cables from the battery, then trace each of them to their opposite ends and detach 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 you get identical parts. Positive cables are usually red, larger in cross section and have a larger diameter battery post clamp, while ground cables are usually black, smaller in cross-section and have a slightly smaller diameter clamp for the negative post. Clean the threads of the solenoid or ground connection with a wire brush to remove rust and corrosion. Apply a light coat of battery terminal corrosion inhibitor, or petroleum jelly, to the threads 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 that it reaches the battery post without having to be stretched. Connect the positive cable first, followed by the negative cable.
