Not sure what this looks like. When the motor is running, the belt will show some minor vibrations, but nothing that should be described as "jumping". Could possibly be the idler pulley spring is too loose and not putting enough tension on the belt. With the engine NOT running, how tight does the belt feel? - should be pretty snug.
