The problem is not with the node or boards. the problem is that splicers think that screw is a c-screw and back it out. Once it comes all the way past the threads in the so called finger it can be very difficult fix and may require removeing all pin connectors on the side of the houseing and the plate that covers it. What happens is the center conductor is not making good connection to the board, its just laying agianst it. It may work for some time that way depending on current draw on that leg, but it can cause alot of intermitent return problems. If you have found this in one node you'd better check them all. If you have any other questions or need someone to do it give me a call. Rick 443-871-1890
