I was driving a locomotive on my layout when suddendly the whole system and the Mobile station died. I don’t think that the reason would be a short circuit because then the system just cut off the power from tracks but doesn’t switch off the MS. In addition, I bought that MS about two months ago.

First things to check:
1) Unplug the AC adapter (wall wart) and test it for voltage (DC) using a multimeter. Is it still providing power?
2) Check your track box and the pins on the cable to the MS.
3) Could there be a short on the tracks? I have had one of the power leads detach from C Track and it made contact with the other one.
I don't think that I have had a situation where my MS has automatically shut off during a short. Usually I hear a sound and press the "Stop" button and then look for the source.
Does the MS power up when the track box is disconnected from the tracks? That would indicate a problem on the layout (not the MS or track box).
Do you have a classic analog transformer? If yes, unplug the MS and the track box and connect the old transformer to the track and see what happens.
If everything works, this will indicate that the problem is with the track box/MS unit. If there is still a short (Train or track), the transformer will let you know.

Hi
Thanks for your message. I guess that the reason for total shut down is maybe the transformer. It’s over 10 years old and when I recently test it with 16V incandescent bulb, nothing happened.

To be clear: do we talk about a mobile station 2 https://www.maerklin.de/...te/details/article/60657 ? It has to be used with a Gleisbox https://www.maerklin.de/...te/details/article/60116 and a dedicated power supply, not a transformer... Or did someone sell you an antique Mobile Station 1 https://www.maerklin.de/...te/details/article/60652 ? This one had to be used with a transformer - and the MS1 tends to die by burning the H bridge output. I have two, one is dead but can still serve as slave for the other, but I take care to stay below the 18VA nominal charge just to preserve it a little bit. They serve, mainly, to program some mfx decoders with new names. If you have a MS1, replace it by a MS2. I'm sorry, that's a price to pay, but with the MS1 you will not find your luck.

I have the Mobile station 2 but I already managed to figure out that the faulty transformer caused that blackdown. I replaced it by the new one and everything worked again.

Before he did used transformer but did he bought a new one transformer? Sorry but it´s not my fault how i do read somebody comment. I don´t get...how can someone use transformer when it stand only power feed use 19VDC for the black box 60116 to start MS2? |

It could be a transformer with build-in rectifier, like the 66181, or it could be Valentin using the word transformer for a SMPS. You've done the same multiple times  Per. |

You can only feed MS2 with dc power via black box 60116. Goofy fact check: The 66360 has 18 V DC, not 19 V DC. The MS2 works with track boxes 60112, 60113, 60116, and more. Colour of the track box does not matter. The track boxes work with AC or DC. Fact check: 100% successful. Originally Posted by: Goofy I don´t get...how can someone use transformer when it stand only power feed use 19VDC for the black box 60116 to start MS2? It is probably pointless to ask for a link to that piece of information. Is there a link? |

Actually, Märklin site says that the boxes need a 66360 or 66361... but elder notices indicate a transformer. Just, you can not buy it new any more (60052 discontinued in 2011).
