I have just added a DCC capability to my new K-27. It is the plug and play Digitrax DG583AR, It plugs nicely into the tender board and the loco runs fine with the locomotive and tender lights working correctly in the correct direction. I assigned functions for the class lamps, firebox light and cab light and they are working nicely. I will soon add a Tsunami sound system to complete the installation. My problem is I cannot produce any smoke. I looked down the stack and have added about 8 drops of smoke fluid but there is no action happening in the stack. The front smoke switch is set to DCC. I tried setting it to DC but it had no effect. Any suggestions? I am also looking for ideas for connecting the Tsunami "chuff" wire. I have not seen any references on the list to installers of the Soundtraxx products with synchronized chuffs.
