OK brought it to another friend with a prodigy 2 and we got it running by changing the CV to 8 but we couldn't do the SV because I don't know it.  I'm not even sure if CV 8 is right for that loco, I think it is.

same results at my friends, and yes I have regular DC locos running & tracks clean etc. It's driving me nuts! hehehehehehe

 I have a Bachmann DCC on board "CSX" sd40-2 that's not working, when you put it on the track it doesn't do anything unless you jiggle it around and that only get's it to spurt. I'm using a E-Z Command controller and have tried it on a  friends similar layout.
The guy whole sold it to me said he had to program it to the unit #8868 to test run it but then back to 3 and it was running fine. it won't even run in DC mode. ?
