i just hooked up my n scale test rack to my zephyr testesd the track for power, cleaned it and then put my loco on there and it didnt light up or do anything so i thought maybe theres a problem with the zephyr so i hook up the zephyr to my ho scale test track and both engines worked does anyone know what could be wrong. the hobby shop i got it at tested it and it worked what, maybe i need to reprogram it but then id have to dig for my manual does anyone know the procedure for reprogramming a new number.
