I do know quite a bit about Lenz, decoders and sound units

I do know pretty well what Im talking about
What I wanted to know was why wont the Goose move when its sound is going well,
Sherlock Holmes and Watson are on a camping trip. Holmes asks 'what do you deduce from what you can see'? Watson replies that he can see various constellations so that it must be winter. Holmes responds, 'No you idiot. It means someone has stolen the tent!'
My suggestion is that you need to look for the tent. In this case the decoder. That's the 'thing' in the loco that connects to the motor. Obviously physically, to ensure that it is present, and how it is connected, but also electronically to ensure that it is working.
Anyone who asks 'why should I reset the decoder' has obviously no experience of decoders. Of the myriad of CV settings how do you know that any are compatible with your system? Frankly only a complete novice would ask that question.
My advice -
Step#0: physically identify the decoder and how it's connected.
I'm not aware of any standards that cover dual DCC / radio control. You need to understand how the various switches are connected.
Step #1: reset the decoder!
Then if you still have problems
Read the CV values for decoder manufacturer, type and DCC address.
I'm omitting step by step detailed instructions because if you need them, really you should not be attempting this.
And only then, if you still have problems, ask for help. HINT: at each step carefully record what you did, and what the outcome was.
Yours faithfully,
Sherlock Holmes!
