Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation, and corrosion, as poor connections can lead to starting problems and decreased engine performance. Check the cable-to-terminal connections for cracks, loose wire strands, and corrosion; white, fluffy deposits under the insulation indicate corrosion and necessitate replacement. When removing cables, always disconnect the negative cable first and connect it last to avoid shorting the battery. If the vehicle's stereo has an anti-theft system, ensure to check relevant information before detaching the cable. Disconnect old cables from the battery, tracing them to their opposite ends to detach from the 
Starter Solenoid and ground terminals, noting their routing for correct installation. If replacing cables, take the old ones for comparison, as positive cables are typically red and larger, 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, then apply a light coat of corrosion inhibitor or petroleum jelly to prevent future issues. Attach the cable to the solenoid or ground connection, tightening the mounting nut or bolt securely. Before connecting a new cable to the battery, ensure it reaches the battery post without stretching, connecting the positive cable first, followed by the negative cable.
