Roco 72250 DC Smoke Generator Issue

I have a brand new Roco 72250 BR 23 002 locomotive. The locomotive is standard DC. I picked up a Seuthe #10 smoke generator, the one listed in the Roco manual. When I installed it the smoke generator works only when the locomotive is running in reverse. Forward I get no smoke at all! There is no mention in the manual about switches or settings. I have several other Roco, Fleischmann, and Liliput locomotives that I installed Seuthe smoke generators in and I have never had this problem! Can anyone help me.


  • Hallo,

    I suspect that there is a diode (rectifier) somewhere in the circuit which prevents the current to run through the smoke generator when running forward.
