New day, new problem. Had been making headway finishing up my yard area. Have about 10 ucs tracks. Most had been working off track voltage, some never wired at all, some wired by a friend to a rail bus which effectively ran UCS on track power. Changing all to fixed power source. Found one with wire so brittle the insulation literally fell off in chunks when the wire was bent. I have the correct cable, but in the course of rewiring the controller, I got something mixed up and the ucs and controller which were operating perfectly until I tried to fix something that wasn't broke are now broke.
Can somebody post a schematic of the wiring. My Lionel repair manual by Greenburg has 5 pages of info and diagrams which all contradict each other. To make matters worse, I took apart a perfectly good controller to see what I had done wrong in the first one, and although I was sure I put it back together right, it now fails to uncouple, but does unload.
Please assist!!!
