To diagnose a bad battery cable, first visually inspect the cables for any signs of corrosion, fraying, or damage. Then, use a multimeter to check the voltage drop across the cable while the car is running; a significant voltage drop indicates high resistance, suggesting a faulty cable. If you notice starting issues or dim lights, these can also be symptoms of a bad battery cable.
