Hi all need your wisdom please in fixing a digital train 37195 sbb haversack steam loco that is stuck in full speed.
Have turned the whole track set off at the power point, taken the train off the track and when I put it back on and press stop to go it goes flat out even though the speed controller is set at zero. Other trains work fine. Using MS2.
Thanks in advance.

Look for short circuits in the loco

He's told you the catalog number of the loco ...

Alan, a catalogue number doesn't mean what type of decoder is in the loco,

thank you

John

thanks John yes that's whats exactly happened it hit a dead spot then went into full speed and was not responsive. So will try to turn everything off see if that resets it.
Other than deleting the loco out of the controller and then re registering it there doesn't seem to much more that can be done?

Your locomotive is a recent model and should be equipped with a mfx+ decoder.

I see two possible situations here...

1) Your decoder is no longer functioning (recognizing the controller) and is responding as would an analog locomotive. If the decoder is toast, you may need to replace it.

2) Your decoder is temporarily thinking that it is in analog mode and not responding to the controller.

Here are a few tests that you can do:

1) Unplug the controller, wait 30 seconds before reconnecting. Once done, enter the locomotive's address and see if the locomotive responds to the commands in digital mode.

2) Remove the locomotive from the track and place it on an analog track. Test to see how it operates on a regular analog track (loop). Does it respond to speed commands?
If it responds normally in analog mode, turn the power off and place the locomotive back on the digital layout and see if it responds now.

3) Check your MS2 to ensure that it issues commands in mfx, mm and dcc. See if you can access the locomotive using regular MM (Maerklin-Motorola) address directly. That address should be listed in the manual. Create a manual register for that address to test.

4) You can place the locomotive on your programming track and instruct the MS2 to detect the locomotive. See if normal operations resume thereafter.

Jonathan, I operate a different system (ECoS = ESU) but in my case, I took the loco off the track and put it back but it didn't make any difference but my decoders have RailComPlus similar to the mfx self recognition mode and eventual it re-registered the digital mode, I think if you follow Mike's advice you should be on the right track

John

Is there anybody near you where you can try the loco on their layout. Also did you try to change the decoder.

Yes, the reset to standard settings is CV 8 by the locos manual page 22.

Do you have access to a decoder tester or perhaps a CS 3 nearby?

It sounds silly, but it could really be defective while it is brandnew. I made experiences with electronic chips, motherboards and similar elelctronic devices, either they are defective pretty soon while they are brandnew or never. But it always were computer, printer, etc. and never a decoder.

Unfortunately it also is not a mfx+/DCC decoder. But what you may try is switch of the mfx+ format and try to install it under the MM format. Digital address by the manual registration shall be 35. But I cannot promise you, if this way is possible at this loco by a MS 2. With a CS 3 you have always the choice to drive a loco directly by its address. If this does not work, than it is a case for a return to Märklin.

Hi Jonathan,
I sent you a PM.
Mike

You sound like a PQ guy.

A joke

Serge,
this is not nice, what you are planning to do with the poor people down under. Then send this Canadian beau further, directly to the Antarctica and hope this sunnyboy does not melt the ice there.
Ah perhaps get Merkel onto the same plane to the Antarctcia. Then the ice has a chance to survive by her coldness without any alternative.

ciao

Well, Germany is a federal state too and similar to Canada. You got Provences and Territories, we call them "Bundesländer" (federate states).
But of course I do only know an excerpt about canadian politics. This was the reason, why I say take this female Staatsratsvorsitzendenkanzler Merkel on board too. Because the effects in their politics are quite similar to the people in both coutries.

I think we have moved a little away from the original topic; but I have to ask:

Were you in the Stade de la Meinau in Strasbourg on the 19/6-1984 ??

I was there.....

Well, the scores says who won, if it was the best team I don't know; but I know it was the most emotional game I've ever seen

Some of the Danish fans were literally crying after 38 minuttes; but then the game changed

After the game, the Danish goalkeeper Ole Qvist threw his shirt to the Danish fans

You can see the shirt here again; but this time in Mexico 1986.................
