Woodone,
Thanks for the picture, yes I see how you did it. It looks similar to what I am doing but with more metal removal. [ Guests cannot view attachments ]
I am done for today and photo above shows where I got to.
Seems my rear light and pick up is going to work too.
Caps fit in well.
Just now messing with my decoder, for some reason in the tester it won’t run the motor or change light direction. Am doing a reset and reload with a different sound file to see if it’s the sound file or a damaged decoder.
Update: the decoder is good, must be a dodgy file or download. I can fix that.
Later update: I fixed it. Either I was uploading it wrong or it was a dodgy download, I know I had interweb issues that day. So all is good. Phew! .
