Need Pinouts for PS-2 10 pin Tether Male Plug Please

It is a straight pass thru harness.  Red/Black/Yel/Wht are the thicker wires for motor and power.  How they are used in an engine especially 5V engines with board in engine can vary.  Look at the engine side PCB of a RK 3V steam and you can see the typical layout.  G

The presence or absence of the mux board also changes the pin assignments.

Ok thanks guys. I should have been a bit more specific; I meant the "standard" pin assignments as they are used in and upgrade kit for instance.

Thanks, Rod

That's the reason they say don't just randomly swap out tenders. There wasn't a specific standard.

The upgrade kits do have a standard.  They're exactly like a plain RailKing PS/2 steamer with no mux boards.

I had 3 tethers on my bench some time back. All three were different. That was enough to tell me to trace from then on.

You may get lucky with the chart and it will match. You'd better trace and make sure!

I've installed a ton of PS/2 and PS/3 steam upgrades, I don't remember ever seeing any different pinout of the locomotive harness.

Clearly the color code on your chart is wrong for smoke fan.  They are standard for typical 10 pin 3V steam.  Even mux, the only difference is the HL wire is the MUX signal from the Mux board.  But position is the same.  PV generated off the diodes on the bottom of engine PCB or diodes off the motor terminals for some engines.  G

George, the most recent upgrade kits now have some different colors for wires, surprised me.  The biggest difference is red for PV and not purple.

The request was for the pin out of the 10-pin connector.  If you're talking about my chart, it was from the ASC manual.  I realize they don't use the right colors, but the wiring was the thing I was trying to convey.  If you are looking at the harness, it's easy to follow a different color wire.

Hey guys I appreciate the chart you presented John. Helped me nail down the problem. I did see that a couple of wire colors are different than what I was used to for PS-2 3V, but diagramatically the hookup is right on. Problem was the orange tach output was shorted to the boiler shell on an upgraded K-Line scale Mikado. This took the boards out of course. So I fixed the short issue and swapped in a spare board set, and all is well. Now I wonder if the boards are repairable? Anyone seen this kind of failure before?

Another thing, does anyone know how to activate the tender marker light toggle in the soft keys? It's there for several other engines, but not in this sound file for some reason.

Thanks, Rod

Boards may be repairable, but have to test.  IF just audio/speed control, and such possible.  But if AC gets to the processor chip not repairable.

I have not seen a new upgrade kit for steam, but not sure why they would do that.  So what color is AC pickup?

Either way the pin out has been standard for steam.  How the pins are used at engine or tender can vary. G

 PS: Some RK SF do not have markers turned on.  You can try a conventional reset to see if they come on, but may not.

Most of the colors are still the same, but switching the purple for red threw me, I don't understand that change.

Maybe just a one time thing due to color availability during that partcular run of kits?

Odd to say the least.  I suspect those are being fabricated in China, I doubt that MTH is making them here.  That being the case, I'd expect them to at least get the colors right in the harness.
