hello,
now my next problem. lol  my son's big hauler seems to be losing his front drive wheel.  it loosens up, comes out a bit then of course binds up.  any suggestions as to why this is happening and how to fix it?  Thanks again!

hi guys,
thanks for the responses.  i ended up having to pull the top off the tender and found a disconnected wire on the speaker.  a quick solder and it is working great!  Thanks!

just bought some used g scale trains.  ring master and suwannee river special.  the sound tender on the special is not working.  can it be fixed?  how do i take it apart? i have swapped tenders with ringermaster train and i get sound. the suwannee tender seems dead.  new batteries and all of that.  is it easy to repair?
