A wire came loose in the control unit. I disassembled the unit in order to solder the wire back. Now I cannot get the unit back together. Is there a diagram somewhere that shows how those plates come together? And how do you keep them together as you are screwing them down? Thanks very much.

I just refurbed six of the controllers for my layout.  You start with the bottom brass strip and then used a square spacer between the next three strips.  Note that there should be a tiny round spacer with a nib at the top and bottom.  That goes between the second and third strips from the bottom in the hole in the strip to stay in place.  Notice that for the 2nd, 3rd and 4th strips from the bottom you alternate the solder tabs so that they do not touch each other.  I was able to hold the stack down with one hand and then insert & tighten the screw.  Good luck and I hope my instructions were clear.
