Thank you Karst, much appreciated. I have verified all the wiring and include the following diagram to show all wiring between each component and the 4 track pieces which are all fully isolated on each rail. Also, the DC power source is separate to the DR5033. The LEDs are part of the MP5 switching but the power & circuits are separate - just there for clarity.?
For the life of me I do not understand how the DR5033RC produces the 'Reverse' condition upon the switch from straight to branch and then the short only after it returns back to the straight position as per my description originally posted.? Do you see anything physically obvious? Or, should I have to start looking at configuration within DR5033 or DR5088RC?
