  Q: How should you periodically inspect and replace battery cables to ensure proper engine performance on Mazda MX-5 Miata?

  A:

  Periodically check the full length of every battery cable due to any damage, broken or burnt insulation, and corrosion because of bad connections starting difficulties may arise and engine performance deteriorates. Inspect the cable-to-terminal connections cracks, loose strands of wire, or corrosion; white, fluffy-looking deposits under the insulation are evidence of corrosion, and require replacement. When disconnection of cables, always ensure that the negative cable is first disconnected and lastly connected to prevent short circuiting the battery. Unconnect old cables to the battery, follow them to their opposite ends and remove them by loosening them off the starter solenoid and ground terminals, and tracing their route so as to install them properly. Where possible, bring the such old cables with you so that you get them in the same parts since the positive cables are usually red and bigger whereas ground cables are usually black and smaller. Wipe the threads of the solenoid or ground contact with a wire brush to eliminate rust and corrosion and a light smear of battery terminal corrosion inhibitor or petroleum jelly to inhibit future corrosion. Connect the cable with the solenoid or ground connection and screw the mounting nut or bolt. Make sure that the new cable should not stretch and you should first connect the positive cable and then the negative cable before you tie the new cable to the battery.
