I have a Lionel 6-28072 J3a Hudson with R/s I get signal sounds but no Railsounds. There are 4 boards. Mother board, receiver board, R/S power supply R/S 4.0 w/2 chips. Since I have no way to test them, should I replace the R/S power supply board ? Ay suggestions?
Thanks for the suggestions. One of the first things I checked was the R/S & S/S switch in both positions in case it was wired wrong. I also noticed I can get whistle or bell in either position.
The RS/SS selects Signal Sounds when the switch is closed. So it sounds like either you have a short in the wiring or something is amiss with the actual RailSounds board. Have you tried swapping another board in? You can try any diesel of steam RailSounds 4 or 5 board to see if the wiring is suspect or it's the board. If the new board still only gets Signal Sounds, you have a wiring issue. If the new board does full RailSounds, the original board is probably bad.
