Hello, was wondering if anyone could help me out? I recently bought a santa fe 5012@ a local train show. It was a great deal and my 4 3/4yr old son fell in love w/ it! It runs great,lights come on and smoke element works! The only thing that doesn't work is the sound board on the tender. This is the 1 plug model w/ speaker port on bottom of tender. I know that it is powered by the track and then the loco but it doesn't seem to be powering the speaker. Any help or advice would be appreciated, thanks.
