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 reconnect it last to avoid shorting the battery. Disconnect the old cables from the battery, tracing each to their opposite ends for proper detachment from the
Starter Solenoid and ground terminals, noting the routing for correct installation. If replacing cables, bring the old ones to ensure identical parts, as positive cables are typically red and larger, while ground cables are 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, and ensure the new cable reaches the battery post without stretching before connecting the positive cable first, followed by the negative cable.
