@Dtrainmaster posted:Only to the Auxiliary Power Supply terminals, Not the ACC terminals. I hope that was a mislabeling in yellow above?
I cannot tell which wire is attached to the solder tab marked RED, I assume it is the one for the RED push-on connector. And unless there is some obscure note in the box about selecting different attachment positions for different outputs, then normal connector assignment would be BLK to outer rail, which is track common, the same as layout common ground. Given that, it looks like BLK/common ground in this case is going to the Left terminal of the Auxiliary Power Supply. Am I seeing that correctly Stan?
What I am trying to establish here is the actual common ground terminal of the Auxiliary Power Supply connector, regardless of the nomenclature used by the mfg. That is what caused problems for the application diagrams.
Yes, I was sloppy in inter-mixing Auxiliary and Accessory. I updated the diagram you refer to. AUX is the 2-wire terminal that supplies power to the 153IR...this typically comes from the Accessory or fixed-voltage output of a train transformer. TRACK is the 2-wire flying-leads with push-on tabs that can supply power to the 153IR...this comes from 2 tabs (outer and center rail) of a FasTrack track section.
The upper left corner of the photo is the bottom view of the 2-terminal AUX power input. So indeed that is showing the black wire going to the left terminal.
Again, if you believe you can get your arms around this and explain it in a way that does not require a degree in Nuclear Physics (Lionel's words, not mine 
) then have at it! As per above, I can't even get Aux and Acc straight...using them inter-changeably which only adds to the confusion. Also note that A and U can be confusing too:
U is NOT necessarily "ground" or "common".
