White front, Yellow rear and blue common, seems that there's a problem with the decoder, swapped it out for a Digitrax board and it's fine now, apart from doing my usual trick of mounting the board the wrong way round, yet againwhat color wires did you link to your back up light?
Yeah, it's only a cheap LaisDCC decoder, not top notch I know, but for a second-hand loco, it does the job, well, usually.Ya can't get any more correct than that.
