Sparking at the junction of the Booster connections

I have installed 2 boosters on my layout and I'm using C Track. I have installed the red tab isolation correctly, however, whenever a loco crosses the junction, there is sparking from the track - sometimes it causes a short circuit. Do I need to install "ski jumps" or is there another way of resolving this problem.

What type of controller / boosters are you using?
I think there were some caveats with older boosters, the later 60174 / 60175 boosters only need isolating between sections - no ski jumps needed.

Hi! Originally Posted by: Drongo  Do I need to install "ski jumps" or is there another way of resolving this problem. When the red and brown wires are swapped in one part of the layout, there will be sparking at the junction. Double-check wire polarity. A mix of power supplies (16 V AC and 19 V DC) can also lead to sparking. In a homogeneous configuration (controllers and boosters from the same family with same power supplies) there should be no heavy sparking when used properly. |

I started my ”booster journey” by the Millenium, using a Delta controller as booster deriving serious sparkles between sections. Now, feeding both a CS2 and a 60175 booster with 60041 power packs, there is no indication of that at all, even without ski jumps. |

And EcosBoost 8A at 19.0 V Different voltages can lead to some sparking. Wrong polarity will lead to heavy sparking. Do you get the sparks only between 19.0 V and 17.3 V? Or also between ECoS and ECoSBoost 4A? |

Hi Tom,
I get the sparks at all the junctions, and the stronger sparks at the 19V/17.3v junctions |

No, you don't need to use the ski jumps, but you do need to physically isolate the 2 sections from each other otherwise the power from one booster will feed into the output of the other and vice versa. That usually leads to smoke. I'm using 2 60174 boosters without ski jumps and have no issues with them.

Mine is powered with the booster in my CS2 and three 60174/60175 external boosters and I have never seen a spark nor have I ever had any digital problems. More of the undocumented mysteries of Märklin I guess. I emailed the NA Märklin dudes about a pretty simple issue and I never received a useful response, so I believe that we are once again on our own here. I see answers on this forum that both indicate that we need to use them and that we do not. I think that Tom provided us with the clearest and most accurate answer, so I would proceed from there if it were me. |

Hi Tom and everyone,
Today we spent about 4 hours trying to resolve this problem without success. I think I have tried everything - the last thing I did, was to put 4 red plastic isolators on all 4 prongs i.e. both the centre rail and the outer rails, and this didn't work out - still sparking.
More information about my layout :-
I'm using C Track, EcoS controller, EcoSBoosters and TrainController. Because I'm using TrainController, I have cut the C Track so that the 2 outer rails are isolated, therefore, one rail is for grounding and the other rail is for s88 detection. AS it's quite a large layout ( 5 metres x 6 metres) there are a couple of places where the 2 rails change and the ground rail connects to the s88 detection rail. There are isolated with the red plastic isolators, but could this cause the sparking ? |

You might try reversing the wall plug on one of the booster power supplies to check if they are in phase. If the wall plugs are keyed to go in one way only then phase shouldn't be an issue. |

The changing transformer plug around is ONLY RELEVANT when using analogue.

I would try to make sure that all of your controllers/boosters are powered from the same power bar. That way, they are all on the same circuit and receiving the same feed.
I don't know how combining 17V and 19V will work. I would think that in that case, full isolation (all rails) would be needed at the junction.
As far as the ski jump/rocker/see-saw is concerned, those terms are all appropriate. The bridge allows the slider to switch from one circuit to the next and pivots for smooth transition, hence the jump or see-saw reference.
@Drongo, if one rail is for ground and the other for S88 detection, how does this work as the non-insulated wheels on Maerklin loks, cars and coaches are bridging the two sides at all times?

That and the fact that NZ/AUS mains plugs are keyed for one way insertion - they can't be reversed like US/European plugs can. You'd have to open up the plug and change the connections.

Thanks again for your thoughts. I did some further research today and I was able to determine a location on the layout where there were only 2 tracks that joined the 2 sections. I disconnected the tracks so that the 2 sections were physically isolated and then I tested the track with my multimeter to find that the ground rails had a connection. I assume that this is not correct and that somewhere there's an incorrect bus connection. Am I correct with this assumption ? With about 200 bus connections to examine, I might be some time before I find it.  |

Something strange and obscure is going on with your layout Greg. Although in theory your mix of digital components from various companies should work just fine, I suspect that is somehow the culprit here. Keep investigating and reporting to the community and in time I bet that we will find a solution.  |

The ski jump/seesaw/thingy is designed to lift the pick up shoe off the centre contact momentarily as the loco crosses from one section to another. Adding the red isolators under the c track will isolate the sections from each other, however the moment a loco crosses the join it will be temporarily connected with the potential for sparks. I think a photo would clarify for everyone and perhaps assist in further advise

I have previously reported several observations with high ground leakage voltage from switch mode power packs for both C2/3 and MS2. If the power plug is fitted with EU plug try rotating it or else as BigDaddy says swop the wires internally. I don’t know if this could cause sparks, but worth trying? I would take the multimeter and test AC voltage from the outer rail to a point that is grounded in your house. Do that with each booster district and see if you get similar results. E.g. I either have 170V or around 50-60V depending on how the main plug for the switch mode power packs is inserted. Best Regards and good luck! Lasse |

I think Teewolf got a little confused you can't run both digital and analog
The rocker was for use when connecting boosters but I don't think you need it now

The rocker was for use when connecting boosters but I don't think you need it now The question is who got confused. The centre-rail rockers are needed when you have a transition between analogue and digital parts of the layout. They can prevent problems when you have boosters with different voltage levels on a purely digital layout. |

The rocker was for use when connecting boosters but I don't think you need it now Oh no I am not confused. And yes in some cases you still need it now. Even Märklin demonstrated the use ofthese isolating seesaws in its book #03070 https://www.maerklin.de/...s/details/article/03070/in an extra chapter (page 80 f) "The best out of 2 worlds". On page 81 is demonstrated the "breakdown into digital and analogue layout areas". A picture shows one line in digital mode and one line in analogue mode. Both are connected by 4 turnouts. So you can switch between the lines without changing the rolling material by hands. But underneath the picture (sorry did not find this one yet in the internet) "Important: at the transition points, isolating seesaws must be provided and the conductors must be insulated in each case." If I find the picture for this demosntration layout, I will add it on. P.S.: I like the words "isolating seesaw" best. Because a rocker is a musicfan to me.  But the seesaw priciple of this children toy is exactly what is done with the slider of the loco while crossing this important isolating point. First the slider is going up on top and then on the other side down again. It is like the seesaw toy is acting. The important isolating effect is obtained absolutly totally.

All digital equipment made since the MS1 ( IIRC ) is made with a H-bridge in the output stage, and the analogue and digital parts of the layout can NOT common ground. The first loco passing the transition will make a short on the rails and thus a short between the two systems, letting the smoke out of the digital equipment. I know a way to do it; but think that for most people I would recommend to not even try, since a train with two connected sliders would still make the output stage of the digital equipment burn.

and the analogue and digital parts of the layout can NOT common ground. Sorry, but IMHO that is wrong. You can have a common ground at the output stage only. Since the MS1 you cannot have a common ground between the controller and the transformer that feeds the controller. A common ground between a controller and a separate transformer is no problem. Check out the manuals for the level-crossings, they show this even for MS1. Trains with two active sliders and centre-rail rockers never worked together. But AFAIK Märklin never sold digital rolling stock with two active sliders. |

My assumption was that some would use the same trafo to power both the digital and the analogue part of the layout. Originally Posted by: H0 Trains with two active sliders and centre-rail rockers never worked together. Also correct. ( I realized this later last night; but didn't have the time to go back and correct. My point is just, that for this to work, there are so many things that have to be done 100% correct, that the chances of something going wrong is too big, IMHO. BTW, I also wonder how direction of the locomotive should be controlled, when going from one section to the other ?? Per. |

Most modern decoders have a "Falschfahrbit" (reversed direction bit). When going from digital to analogue and reversing there, on return into the digital area the loco keeps the current direction even if it opposes the current direction set in the digital controller. Next time you reverse in digital, controller and loco will be in sync again for decoders that support absolute directions. |

Well the "Drongo" has done it again. With the help of a few friends we found the cause of the problem - Drongo had reversed the wires into the booster. For those outside the Australian/New Zealand region, "drongo" is a slang term for someone who does something stupid - hence my avatar. Anyway, it's onward now to finishing the layout, but I really feel like a "Goose".

Greg
p.s. thanks to everyone who offered assistance. |

So just to clarify you did not need any ski jumps/ rockers? You simply needed to isolate the center rail connections and your boosters worked fine?
Thanks,
Chris

The rockers are only needed between analog circuits, not digital ones. You want the ground to run through all circuits and just isolate the pukos in the center. |

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time. |

They are needed when connected an analogue circuit with a digital circuit. They are also needed between different digital circuits - for example if you use two digital controllers. Between a controller circuit and a booster circuit fed by the same controller they are normally not needed; the track signals should be identical. |

Tom again thanks and thanks Jim. I had found this thread after I made mine. So anyway I can’t wait to add the booster when it arrives as Santa has already delivered a few more engines.
Thanks again.

A dealer told me that they were needed many years ago, but I moved to digital before expanding my layout to where I needed a second analog circuit. I even bought some M track ones from him, which might be why he told me that I needed them. |
