PS2 5 board question

Is the 5V board set the same for both steam and diesel engines? Obviously different sound files and possibly different hardware to mount to frame.  The question is can I put a 5V diesel board in a 5V steam engine as a direct replacement just loading the correct sound file.

The answer is "maybe".

There were two different 5 volt boards:

  • One was the standard 5 volt board, which was the same board for diesels and may steamers.
  • The other was the 5 volt board that was out into subways, trollies and articulated steamers.

If your steamer isa non-articulated model, then you can swap in a diesel 5 volt board.

John,

I thought that the dealer loader would allow you to customize the name anyway, but I haven't actually tried it.

Yes, that's correct.However, that's a permanent name, not a DCS Custom Name, which is done using the remote (or the app).

Thanks for the additional detail info.  In this case it is a non-articulated steam.  A related question is the steam engine with the 5V board seemed to have just quit working. I think the engine was going really slow and may have quit moving (binding) and shut down. Now no longer works. The engine is on a test track by itself and no longer do I hear the click when it gets the watchdog signal.  Other engines put on test track do fine so comfortable that TIU works fine. 

Does this mean board is dead or could it be the small 5V regulator mounted to frame?  This is a RK engine so don't want to spend much to fix.

The "click" you (should) hear is when you initially apply track voltage - not from the watchdog signal.  In other words, you should hear it even if applying track voltage from a conventional transformer (no TIU).

It's true if that 5V 3-terminal regulator went south, you would not hear the "click".  But the likelihood of that part failing is small.  In all likelihood another cause of no "click".  I suppose if you have it all opened up and can access the part I guess it's worth the 1 minute it would take to confirm you have rectified DC track voltage on the left terminal (over 20V if you have command voltage on the track), and 5V DC on the right terminal - both DC voltages measured relative to the center terminal or metal tab (which is NOT the same as the frame).  You can slide the connector housing to expose the 3 terminals for measurement while still maintaining connector contact.

The 5V board set is difficult to troubleshoot.  Verify the AC track voltage is reaching the board on the 7-pin connector on the smaller power-supply board; you should be able to measure track voltage between red and black wires (2 each).  Then look for anything obvious...leaking, bulging, deformed, charred components.  Aside from that, not sure it's worth going any further.

Barry,

I was not aware of the 5v subway board.  I have never seen one.  Thanks for the information.

John,

I learned when I tried to put a subway sound file in a non-subway engine, to make it do station stops. The result was subway sounds without any station stops.

Thanks Stan  You were correct that regulator was fine. I replaced the board set with a spare and all is fine now.  Don't think I am going to invest in any more repairs of 5V PS2 boards.  In fact, any future purchases of used MTH engines I will limit to at least the 3V PS2 or later unless the deal was so good that I could upgrade and still be a reasonable value.

Good call.  Reminds me of the Kenny Rogers tune The Gambler:

You got to know when to hold 'em,
Know when to fold 'em,
Know when to walk away,
And know when to run.

I figure it's worth rolling the dice on the regulator since it doesn't take long to measure...and if it was the culprit you could be in back in business for $1 or so with no soldering required.
