MTH PS2 5V Identification Help Needed

Searching the Cab number on the MTH Product locator results in this being from 10-1139-1

Here is the PS2 Wiring diagram for Steam engines:

H1000,

Thanks for your reply. I found this already and that’s why I’m struggling to find the correct model it was from. The parts drawing and sound file for the 10-1139-1 doesn’t match the hardware and sounds.

Thanks,

It's possible that the sound file may have been switched at some point. When you add the board to a DCS system, how does it identify?

Why are you worried about what it came out of?  If you're going to use it, you'll obviously load the sound file of your choice and move on.

John,

Yowzers! 😳 lol. That’s a very valid point. Most people would probably do that and move on. I simply reached out to see if someone had a quick answer or valid explanation to the possible discrepancy on the label. Many forum members have a wealth of experience and knowledge from working within the manufacturers and/or industry or have amassed their own information by working on the hardware independently. And some of that information, or discoveries, have resolved issues a few of us have faced with our own equipment. It’s all about the hobby and the sense of community within the hobby. My desire, or compulsion rather, to find what model it came from, will probably result in gathering useless information. However, there’s a slight possibility it may shed light on an unknown fact or problem that might solve someone else’s issue later down the road. Albeit, highly unlikely.
Also, given that has a hooter whistle, it’s easier to put it into a loco that would have had that type of whistle rather than re-flash the sound file because I don’t have a TIU. Although, I could pay you to do it. 😉

H1000,

Anything is possible I guess. I have a few theories and that’s one of them. One thing that sticks out is the MTH website shows the 10-1139-1 was sold in a passenger set. The board is labeled “#4694 Steam SCS-Freight MTH”. Maybe it started life in a 10-1139-1 tinplate loco outside of the passenger set and someone fitted it into another loco and re-flashed it? Maybe it was left over hardware from a model run and the factory installed it in a different model equipped with a different sound file? So many variables. I figured someone on the forum may have a definitive answer or explanation.
As for using the DCS system to identify it, I haven’t purchased a DCS system to do so. Almost all of my inventory is TMCC or Legacy. I have a few PS2 & PS3 locos that I run conventionally. So I’m outta luck there. Btw, thanks for the diagram. Much appreciated.

FWIW, I've found a boards in locomotives that obviously had changed sound files, I never gave it a second thought.  If I test the board and it's fully functional, I load the sound file and move on.

Agreed. That’s the most efficient way to do it. Well, I’ve set it aside for now. I’m finishing up on a few other projects at the moment. I’ll figure out what to do with it at a later date.
