I bought myself a Dynamis By bachmann and i have a dcc equipped loco and its never been ran before (straight out of the box) and i want to know if the #0003 (factory installed in the decoder i think) would work with it then?
What does the locomotive manual say? If it came without a manual, why not try it and find out? But keep in mind that #0003 (long address) and #03 (short address) are two different addresses. Normal practice is to program factory installed decoders either to #03 or to the cab number.
