I have an Econami sound decoder fitted to an On30 Porter conversion, which up to now has run perfectly. When I put it on the track yesterday and opened the (NCE) throttle it dashed forward and ran into the bumper. In reverse it ran smoothly and controllably, but when I again tried to run forwards it would not move. When it did eventually move forwards it was very jerky, but remained smooth in reverse. The sound continued both ways in line with the movements. As an added annoyance the lights will not work either way although the generator sound can be heard.
I have tried resetting to manufacturer's settings, but that makes no difference.
Any guidance would be much appreciated.
