just hooked up my DCS system. MTH engine works fine. I have a conventional engine on fixed output 2. The engine runs when I move the transformer handle but either the horn or bell Buttons work. Any ideas?

Not sure what you have for a transformer but if it has a whistle and bell button they should be working. Fixed 2 is a straight through connection with the dcs signal imposed on it. A conventional engine will disregard the dcs signal. . what engine and what transformer? I don't want to get in to setting up a var channel just yet with the signal turned off.
i'm using a MRC 270 dual power transformer. The bell and horn buttons worked before I hooked up the system
Just a hunch, however, try reversing the wires coming from the transformer, going into the TIU channel input.
I use a MRC 270 dual and I know that my conventional engines respond to both the whistle and bell buttons, even when funneled thru the TIU first.

Barry, I switched the wires as you suggested and it worked. Thanks all for your help.
Another question On the loop that has a insulated track section I'm getting a "check track" message when I try to find an engine or access the horn or whistle feature. Any help?
Vinny,
More details, please.
I have two loops that are wired for DCS. The outer loop has no issues. The inner loop has a stretch of four insulated tracks. I cannot find an engine when the engine is on the insulated tracks. Also, when I try to blow the horn or whistle the engine does not respond. Once the train is off the insulated tracks the engine responds nornally. This is the same loop that I asked you about when it came to running conventional trains on. I was able to access a TMCC engine on this loop
Just curious whether your feeder from the tiu output(black) to the outside rail is connected to the same side as the insulated rail?. That might even leave a dead spot. If it is, try putting the feeder on the opposite outside rail . What does the insulated section control??
Vinny,
My best guess is that the path back to the TIU on the Common wire (outside rail) is not very direct. It's possible that it's traveling through the wheels on a car or the engine's wheels.
Try temporarily connecting the insulated outside rail directly back to the TIU's Common (black terminal) output. See if things improve.
Vinny26,
Along with what Barry and the guys are advising you it almost sounds like you have a section of bad track some place in your inner loop, I would test every piece of track in that loop.

Thanks. I guess I need to check each section of track
