Mike can you give a better pic of the electronics in the tender? You may have cruise and it may just be off. From what I can tell looks like you have the ERR Railsounds board mated to a ERR board of somekind.
So you are stuck at two chuffs, the switch under the cab doesn't switch back and forth from four to two chuffs?
Not sure what Pete is saying. ERR cruise commander will have no issue using the micro switches for chuff. The way this 3rdrail engine is wired, is the turbo smoke unit got it's chuff trigger directly from the micro switch one wire lead to the turbo smoke unit, the other to the tender for the railsounds.
