Hi. Just finished powering all my points, which are Peco 75 Bullhead (which claim do no need isolating fishplates) and have powered the frog. I am getting power overload messages on my Prodigy Advance 2 (I guess this is caused by a short circuit) when a train passes over the join indicated. Not in both directions. The top and bottom arrows indicated the direction of travel. It hasn’t been the same in the opposite direction. What am I missing? NB other points on my layout have been wired similarly and work ok so I wonder if this is unrelated specifically to the points but to something I’ve done wrong? Or something else.. Thanks!
