Alco 2-6-0

[nywarthog]

New Alco 2-6-0 only runs at a very slow speed I have a MRC Prodigy system I have programmed the decoder to start at 3 volts with a top at 13 volts, I did not change any CV's, only address. Any suggestions?

I am curious to know how you managed to program the decoder without changing any CV's.

My guess is that you accidentally reprogrammed one of them without realizing it.  Best bet at this point is to reset the decoder back to factory settings and go on from there.

Here is a link to the Alco 2-6-0, CV's. Store the link in Favorites. You can donwload and print it out if you prefer.

Because the MRC unit allows you to set "SV" (Start Voltage)  "TV" (Top Voltage) "AC" (Acceleration) etc. without actually putting a CV value in

Thanks, I'll try that, although as I said I didn't change any CV's other that what the MRC unit guides you through.

Maybe this can help. Little different problem but the reset may help you

I am surprised that the list of CV's does NOT include a reset.

Programming at a higher level (using the names of CV's rather than their numbers) still requires your command station to send commands to the decoder via the rails.  I do not use MRC technology but do use a computer running JMRI for much of my programming.  Like your Prodigy, my system communicates via the rails with the decoder it is programming.  Once in a while, the result of the programming is not what I expected.  In these rare cases, examination of each and every CV shows one or more that has changed even though it was never altered in the higher level programming.  I do not really know the cause of this but suspect it is marginal contact between the locomotive wheels and the rails during programming.

First, I'd like to thank everyone for trying to help me out here. I finally went to the Soundtraxx web site and followed their instructions to re-program the factory settings, the instructions can be found here;
http://www.soundtraxx.com/manuals/tsunamisteam_users_guide.pdf page 12. It involved setting CV 30 to value 2 on a program track, then placing the locomotive on a powered track and letting it recycle. You were probably right that one or more CV's were set to the wrong values, however since the engine ran this way right out of the box it must have occurred at the factory. Again, thanks.
