With the abundance of lighting functions and wanting to see and check them before I placed the shell on the frame, I decided I needed a way to see what was happening!  I went to work and prototyped a small connector board with LEDs so I could put the frame on the test track and test the motor, speaker and lighting functions before assembling the locomotive.  The Light Test Board is also a good diagnostic tool to see if the decoder and motherboard are behaving properly!

The Light Test Board works with the 8 output Original Decoder Buddy, and both the 12 output V5 and V5B.

    Great price, Service and Works...

    I bought a DC Thern at a meet. My intention was to put in a decoder with sound and I needed some advice on how to do it. I then saw an article in a magazine that mentioned the Nix Trainz decoder buddy. I was having issues with the install so I sent away for the Decoder Buddy and a Test Board. I may be still having issues, but I can see this works better and I think everything will work out pretty soon. I like it and if I do any more projects, I will use Nix Trains products.
