Years ago I had 2 DCS channels isolated with a lift out bridge. No insulator. Over time what was once a slight gap now had the center rails slightly touching. Didn't really notice an issue till I blew a fuse. Didn't realize one blew. Now one channel was trying to handle way to much track. My DCS signal wen't totally south. Spent a few evenings and finally saw the problem. A little more trimming and some styrene and it won't happen again.
