Due to the fact that there appear to be several variations of 153 IR controllers, and different instruction manual dates for some versions, along with conflicting terminology, I have decided to pull the (2) application diagrams and corresponding information that I posted earlier. The copy of the pictorial diagram that Stan posted of the unit he opened, and I marked the modification on, has remained.
Although the modification allowing full use of the relay is still able to be preformed, the number of variations involved requires the ability to determine which of the ACC or COM terminals, and which of the Auxiliary Power Supply terminals, are internally connected to Relay Common. This also affects how the outputs correspond to Transformer Common/Track Common/Layout Common Ground.
If at a later date, simple but accurate diagrams, like the one that Stan posted of the unit he opened, are made of at least the 3 known variations (A-U, U-A, Power Supply - for auxiliary input) I will re-post application drawings based on those.
