Re: programing a decoder thats not in a loco


I use mostly ZIMO decoders and the no-no was through their USA distributor. A lot has to do with speed testing and back EMF that the decoder is looking for.  A resistor can't provide back EMF. I use an old chassis and have it set on test rollers. Since adjusting speed is part of the decoder programming why use a resistor? My logic.
