Connect the positive (+) terminal of the dead battery to the positive terminal of the donor battery, then connect the negative (-) terminal of the donor battery to a solid ground point on the car with the dead battery (not directly to the negative terminal). Start the donor vehicle, let it run for a few minutes, and then attempt to start the XK8.
