Q: How Should I Remove and Replace Battery Cables?
A: When removing the cables, disconnect the cable from the remote ground terminal first and hook it up last to avoid shorting out the battery. Disconnect the old cables from the battery and trace each of them to their opposite ends, noting their routing before disconnecting. If replacing any old cables, take them with you when buying new ones to ensure identical replacements. Clean the threads of the solenoid/ground connection with a wire brush to remove corrosion, then apply a thin coat of battery terminal corrosion inhibitor/ petroleum jelly to prevent corrosion. Connect the positive cable to the battery terminal first, followed by the ground cable to the negative terminal.
