Toyota 90980-07407 Cable, Bond

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.

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. Check 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 that the cable is corroded and should be replaced. 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 or the battery may be shorted by the tool used to loosen the cable clamps. Even if only the positive cable is being replaced, be sure to disconnect the negative cable from the battery first. 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 to ensure correct installation. If you are replacing either or both of the old cables, take them with you when buying new cables. It is vitally important that you replace the cables with identical parts. Cables have characteristics that make them easy to identify: positive cables are usually red, larger in cross-section, and have a larger diameter battery post clamp; 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, make sure that it reaches the battery post without having to be stretched. Connect the positive cable first, followed by the negative cable.
