Put the orange plugs back in and one of the wiper on one end of the nut. use the wiper and screw it and the nut over the screw until you almost cover the first plug. You can now start adding the ball back in. you need to take something small to help the ball back down into the circuit. you have to do 1 circuit at a time. it will take a little time but I have done it with the same style screw many times now.
