To start a diesel with a dead battery, you can use jumper cables and another vehicle with a functional battery. Connect the positive clamp to the positive terminal on both batteries and the negative clamp to the negative terminal on the good battery, then to an unpainted metal surface on the diesel vehicle. Start the engine of the working vehicle, then try starting the diesel vehicle. Alternatively, use a portable jump starter following the same connection method. Ensure all safety precautions are followed.
