Title: How do I install a soundtraxx decoder in a N-scale GP-7 specifically item 62456?
Post by: zpak on November 26, 2017, 09:10:23 PM
I want to install a soundtraxx sound decoder into a N scale GP-7. Please help me to understand how to connect track power to the decoder. The factory decoder has spring tabs that contact the frame. The trucks also have spring tabs that contact the frame. When I remove the factory decoder pc board, I need some other way to connect the decoder to track power. What do you suggest? I planned to drill and tap 00-90 holes in one end of the frame and attach the red and black wires from the decoder to the frame with screws. Should this work? I am having problems drilling into the frame. What is the frame material made of?

When I soldered and installed my Soundtraxx Econami DCC sound decoder into Bachmann GP-7, I desoldered the spring tabs from the stock DCC decoder and then taped them to the chassic. I used all four in case one lost contact with the chassis. I have used mine without fail for about a year now.
