Toyota 90980-07407 Bond Cable

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, trace them to their opposite ends, and detach them from the starter solenoid and ground terminals, noting the routing for correct installation. If replacing cables, take the old ones to ensure identical parts, 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 battery terminal corrosion inhibitor or petroleum jelly to prevent future issues. Attach the cable to the solenoid or ground connection and securely tighten the mounting nut or bolt. Before connecting a new cable to the battery, ensure it reaches the battery post without stretching, and connect the positive cable first, followed by the negative cable.
