Programming GS4

[ToddW]

I have a GS4 4-8-4 - SP Daylight #4449 RAILFAN (DCC SOUND VALUE) locomotive and a DCS52 Zephyr Express controller.  I was trying to change the locomotive default address (3) to something different.  Afterwards, the train had lights and sound, but wouldn't move, no matter which address I used. I tried setting it back to factory defaults using CV8=8.  The train runs but now I have no sound.  I have not been able to find much online about the default train and sound settings.  I have also read that the number of times the light flashes on the locomotive can indicate it's status, but I have not been able to find any documentation on that either.  Any help would be appreciated.

Thanks,
Todd

Have you tried F8?

Check the value of CV 128 the master volume.  If it is zero, try sending it at 100.

 I cannot believe that these solutions above are not somewhere in an online manual for the locomotive or the controller, very peculiar

Thank you for your response. I did find a chart with the default settings. I checked the volume as you suggested and it was set to 153.  I put it back on the main line and tested it again and got sound but no movement or lights. I re-entered the default address, after doing that I got movement and lights but no sound. This is so weird.  I'm sure it's something I'm doing wrong. Maybe I need to learn how to use JMRI instead of trying to do it from the controller.

Thanks,

I've never used JMRI.  It appears to be a convenience to a lot of folks, but it's not something you need.

You need to eliminate your controller as the possible problem source by testing your engine on another layout, if that's possible.  Resetting the decoder to all default values by CV8=8 should get everything to basically function, but the default settings on all these engines usually leaves something to be desired performance-wise, that's another issue for discussion later.
