Ps2.0 rs-3 issue

Are you using MTH transformer, and DCS? Are the batteries in both the engine and the remote fully charged? Will it run in conventional mode?

If there was an over current at one point, there are inductors on the board that can become damaged from the heat of the overload.  The inductance changes and that kills the DCS signal.

You can try cleaning wheels and pickups, replace the wire and try again.  The problem is many of those inductors where custom made for that board, so they are not available.  G

You could probably transplant them from a dead board, right?

I was addressing George as he brought it up.  I know he must have a plentiful supply of dead boards to salvage inductors from.

John, For PS-2 3V Power supplies no since I have saved all the PS boards.  The ones I have not, 1 has been salvaged.

Now PS-2 5V yes your right, but I have not actually run into this on 5V.  In fact I need to see if any of those inductors are the same as on the 3V PS.  G

I should send you a couple of my P/S boards, I have several that I haven't gotten running.

I did invest in an inductance meter some time back, so now I can check stuff like chokes and coils.

Here's the inductance meter I picked up, it's really quite accurate against a few chokes I had of various values.

I just use a little 5V power supply I had in my junkbox.

hi I'm in   need of a 5 volt ps2 board how much would you want for it,i need good board or parts from 5 volt ps 2 board?

I have dead 5V boards, I'll send you a couple for the price of shipping.  If you need parts that aren't already dead, they're the best option.

I'm not buying the board, I'm offering you a couple of the 5V boards so you can scavenge parts.

This is confusing who is on first?  Taz49 sent me the board and it was fine.  No issues.

He did have engine wire damage, so I think the engine hardware needs to be redone to ensure all good conductivity for track power.

RT not sure what your posting?   G

When it does find it, it doesn't find it correctly meaning no name.

I have recently encountered this when trying to add a new MTH engine.  The first time the engine was on the far side of the layout.  The furthest from the TIU.  It added an engine to the address but is did not have a name.  I deleted it, move the engine to the track closest to the TIU and tried again.  This time it added all of the nomenclature information.

I thought that was strange.

The differences between 3V boards and 5V boards, other than the obvious visual appearance like connector locations is as follows.

• The connectors are in different relative positions, and sometimes that requires extending the wiring harness to certain connectors.
• The boards have a different mounting scheme, the 3V board is in a plastic carrier and the heatsink for the bridge rectifier is a different design.
• The 3V board obviously uses a different battery harness with a different charging plug and different battery connector.
• The 3V board requires a 4 ohm speaker vs. the 16 ohm speaker for the 5V boards.

The overall size of the two board packages is very similar.  There are some locomotives that due to the different mounting, it's pretty difficult to put the 3V board in place of the 5V board, and you may have to get creative about mounting the 3V board.  So far, I haven't had to resort to mounting the 3V board in the tender if the original is in the locomotive.
