I saw this question posted elsewhere on the web days ago and haven't seen a response. Could anyone here comment? I'm interested in the big picture of why the connections would need to be reworked at all. Thanks for your time.
I have an issue with a 2126 whistling freight shed that was working fine with an old 4090 transformer, but doesn't like the KW I just purchased and hooked up. I have the shed set up to operate on an insulated track section; when using the 4090, I had the terminal clip at the back under the shed's roof wired to the number 2 clip on the lockon (with nothing on the number 1 clip) and the front clip under the roof going to the "C" post on the 4090. It worked find under that arrangement. With the KW, however, the "C" post does not provide enough voltage to operate the shed, and the "D" post provides 20 volts, which is too much. I've also tried hooking the shed up to the "A" and "B" terminals on the KW, but that doesn't work right either. The track wiring is exactly the same as I had it before when it was working with the 4090. Any suggestions for how I might get this to work with the KW?
