How do you jump start a Ford diesel E-250 van?

To jump start a Ford diesel E-250 van, first ensure both vehicles are off and parked close enough for the jumper cables to reach. Connect the red cable to the positive terminal of the dead battery, then to the positive terminal of the good battery. Next, connect the black cable to the negative terminal of the good battery and then to an unpainted metal surface on the dead vehicle to ground it. Start the working vehicle and let it run for a few minutes, then attempt to start the E-250.
