Can anyone help me with a weird issue with RailMaster and Function 0 on a loco with LokSound 4? The loco's headlights do not operate most of the time - triggering F0 does nothing. I have tested them electrically and they work fine. They work normally when the decoder is removed and the blanking plate reinstalled. The model runs happily and the onboard sound works. However! On a fresh reset of the decoder, when the loco is on ID 3 and ONLY when it has ID 3...the headlights work. As soon as I change it to any number other than 3, the lights go out. LokSound 4's manual says that if F0 does not work, "make sure the controller is set to give loco #3 28 or 128 speed steps". Is there a way to check how many speed steps RailMaster is using with a loco? I have tried duplicating the loco I keep in ID slot 3 just in case there was something about its' particular settings, without success. (I am going to test the loco with a different decoder shortly. That will at least provide more data).
