lost all power while driving, batter cable end burned in 2 on 2004 Jeep Liberty

Was driving down the road and lost all electrical power, pulled to shoulder and looked under hood and battery cable end was burned in two. Touched end to positive post and cable burned. I figure it's a dead short but can't find it.
