Hi again 'Going Spare'
It's non-motorised, as the thread title.
I can't use a select or elite manual either I'm afraid, I use the Roco Z21.
Here's the funny thing, when I fit a [working] decoder to it the decoder doesn't register during programming, no lights, nothing.
Yet when I refit the blanking plate and place on the track the lights work fine.
Also, what directional lights are you referring to?
Place your DVT with the motorised loco on the track and programme the address together ( you can use the same address as the motorised loco ).Then using F0 the direction lights should work .you may have to alter the direction of the DVT so red lights when the motorised is white .
