Went to start my car yesterday and it would not start thinking it was a dead battery I charged the battery and. When I went to start it with the charged battery and when I turned on the ignition the radiator fan came on and a black box behind the battery was clicking I think it is a reley but I'm not sure! Any help I would appreciate! Thanks the car is a d turbo s! And the engine has just been replaced
