QUOTE: Originally posted by johncolley Do you know if you had a minor short, such as going against a wrong way turnout? I have had that happen. Just have to do another reset. I have a pair of them that I run together. I separately programmed one to run reverse with no bell, because the bells will get out of sync and it's not a happy sound. However blowing the two horns together sounds neat! I had a lot of problems early on but have now gotten them set at around 40% sound level and 128 speed step and they are great!
