Help....beating a dead horse. I mean proto sound 2 not working.

It sounds as if the board is shot but I am just guessing. I had a flaky engine and it was the wire to the sound switch that was frayed at the solder but not completely detached. I soldered it and it was fine.

Years ago I had a DAP GS-4 Western Pacific that hadn't ran in years. Hit and miss on operating till I discovered that the tether connection at the socket of the locomotive had cracks around the pins and flexed would quit working. Reflowed the solder and all was well again. Additionally, since it sounds like its a 5 volt board, they are a source of a lot of problems with things going bad up to and not including the larger of the capacitors shooting craps. Good luck and hopefully it's something easy.

Hi All,

We have a MTH DMIR Yellowstone model 20-3030-1that is being crabby.  It will not run, at all anymore.  I have been through the forum posts that I can find on the topic.  Replaced the $12.00 9 volt battery, checked the connection on the harness on both boards in the engine and the tender, made sure all the boards are seated, checked all the connections in the tender, did a factory reset on the sound board.  When we try to run it in conventional mode it just cycles some sound that I have never heard.  To be honest this is an engine that we don't run very often because it has always been a little flakey, but it has never just not worked.  

Anyone out there have any ideas?  It's kind of sad to have this nice of a product that we can't run and just have as a paperweight.

Thanks all.

Did you charge the new battery for at least 14 hours? If not the battery needs to be charged before using, the new battery must be charged before being installed in a PS-2 engine. I recommend the MTH wall charger(can be bought for less then $20.00 at most major hobby shops) for this as track charging is too dangerous where I live because of power fluctuations or interruptions.

Has this engine been upgraded to PS2?  Originally it was PS1 from 1999 catalog.

That locomotive is Proto Sound, the QSI proto 1 version.  It is not ps2 unless someone upgraded it, and even then it would have a BCR-2 or 3v battery.

Do a reset, feature 18, and listen for the 2 toots (that means the reset took).  If that does not work, let it sit on the track for about 1/2 hr at 12 VAC and see what happens.  Sometimes the boards need a jolt to come alive.

It really sounds to me like you should take it to a MTH tech.

please give me a call on this engine  I will try to help you

My bad, it is PS1.  I didn't even realize until you said something.  Thanks Joe.
