Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery because this could trigger a spark that ignites the gasoline in the engine bay.
