I have an MTH Railking GP20 with the 3 volt DCS system. When this engine was last run about 8 months ago, everything including the sounds worked great. I just put it back on the track and allowed the battery to charge for several hours. I started the engine using the start up button and the lights came on but no sounds. It ran fine and all the controls seemed to work as advertised. I have checked the sound button (#4) a lost of times and no sounds. I rotated the volume pot. a number of times without any change. I did a factory reset and still no sounds. I have tried the volume up button about 50 times and still no sounds. I removed the shell and could not locate any wires that seemed poorly connected or out of place.
I am not sure how to check the speaker so that has not been verified.
Any suggestions on where to go from here.
Thanks in advance for any help.
Don
