some background.....I have a completely DCS environment. It has been a while since i last operated my trains. I use the 2 variable channels on the Z4000. Throttle 1 basically operates the lower level, throttle 2 operates the upper level. My lower level is operating fine.
My problem. Turn the throttle to operate the upper level and it is shorting. red light comes on and the Z is humming. There is nothing on the tracks or laying across the track on the upper level. I am sure to take all rolling stock and engines off....still shorting.
I disconnect from the terminal block..so completely taking the layout out of it. I still get shorting.
So that tells me it is happening somewhere on the TIU side...is the actual Z or the TIU....as you would expect and I double checked...red from Z to TIU and black from Z to TIU then the same from TIU to terminal block...but even after disconnection from terminal block still shorting...doesn't it have to be the Z or the TIU?
