Hello folks! This has to be the most fusturating projects for me. You see, the first installation of CN-GP was done without kapton tape and bad quality of solder wire (I believe its not even a resin core). This cause the decoder to fried up. I sent this one back to TCS for replacement thanks to Goof-Poof warranty that they have. Its my first time installing and soldering DCC into locomotive. Obviously lots of lesson learned. First, I bought two new 1/4" kapton tape and a better quality resin core wire (High grade, 60/40, .03, 1 DIA, and 4.0 oz) Once I got required materials, I went ahead and get another decoder (I have at least 4 locomotives that needs CN-GP, so its fine that I got 'two at the moment'). I installed everything according to instruction provided by TCS... religiously. Kapton tape included, better soldering work and so on. The result was much better finish product. I went ahead and put it on DC track and see if I can test it... It does not run at all. I saw small, tiny, flash but that was it. I couldn't tell where was the flash came from (its like bright silver kind of flash). I went back and double check everything. No wire are touching, the motor is separated from frame thanks to kapton tape, no loose wire touching the frame, and so on etc etc etc etc. But one of the things that Im worry about is orange/grey wire being pinched by the frame. The motor plastic frame though do have a notch for the wires to go through. I am at lost. I would love if there's a DEEP instruction regarding to installing DCC (wire) decoder into locomotive. EVEN a basic instruction how to perform solder work. Regardless, what do you guys think is wrong with this decoder/locomotive? When a DC throttle is applied, there is no light therefore there are no pick up. There are no sounds nor motion either. I had one thought that maybe it cant move unless I use DCC application? Thank you for any help provided!
