how is the chuff produced and how does the smoke unit chuff in sync. The engine I purchased does not have the original eob from tas . I am working to upgrade it to cruise commander. The current set up is using a reed switch under the tender, but I would like to use the cams and micro switches in the engine. It appears that the grey wire out of my 10 wire harness is the one that connects to the micro switches when I manually actuate them and reference ac neutral, but each one only seems to work depending on the 2/4 chuff switch. Does one micro switch have a 4 lob cam and the other micro switch have a 2 lob cam? Does the cruise commander use a ac neutral reference through the micro switch? Does the Tas smoke unit use the same neutral reference the chuff Uses to produce smoke in sync?
2nd question. How does the boiler come off the engine to see the micro switches? I do not see any obvious large screws like on an mth steamer.
