I have purchased two Graham Farish class 47s and installed DCC sound into one of them. The chip would not accept the code so removed it and put the blanking chip back in. Boom, the lights still work but no movement. I switched out the mother board with the other new loco and still no movement. Put the good board back into my untouched loco and now it doesnt move either. I have done DCC sound in a few of my other locos with no issues. Does anyone have an answer?
