Hi Everyone,

Ever since I got my 7286 turntable I've been having nothing but problems with that thing, initially it sounded like it was going to die before it got to the next spoke and it always lost spoke 1 and had to be reprogrammed. I later found out that my layout didn't seem to have enough power. Now that I have enough power it works better although the sound of the motor isn't a consistent hum, the motor sound fluctuates. The other problem is that when traveling in one direction it sounds like the thing has sand in the motor, going the other way it's fine. When I hear that noise on a more consistent basis it's almost guaranteed that it will loose spoke 1. A few of my friends have this turntable as well and it's been nothing but problems for them as well, recently one of my friends told me that he read something on the internet stating that somewhere in the decoder book it says any turntables purchased before 2002 should be sent back to Marklin for replacement, if this is really true, I'm sure it wouldn't be in my book since I purchased mine before 2002, could someone please confirm if there is any truth to this information?

Thanks

Mike

Did you mean this link Maxi?

Timaximus

That is the link to the site which offers a decoder with extra features. Here is the link to where one can get the finished unit. http://www.bmbtechnik.de/spezial.html

Hello,
I am considering installing the 7286 TT based on the wonderful TT layout pictures I have seen in the "my layout" forum ("Timaximus: the building proces goes on" and "Mikael - Construction of layout 3")

I use computer control software (RR&C0), interfaced through an IB
I have looked at the site from


and have two questions as my experience is only controlling trains and turnouts using the computer software in conjunction with K83s/Veissmann 5211 and contact track indicators using S88/Uhlenbrock 63350 hooked to IB.

1. Does the item above take the place of the Marklin 7687 digital retrofit set? This is the description of the device from the site listed in the quote above, "Turntable decoder (design Sven Brandt) as ready-made device for the Motorola data format"

2. Do I need a K84 or Uhlenbrock equivalent in addition to the item above or does this decoder connect directly to the IB which serves as the computer interface?


Thanks for the help

This device replaces the Marklin 7687 digital retrofit set and connects directly to the track forthe digital signal and to a transformer for the required power to operate the module and lights.

I would advise to purchase the completed module and manual operating box from Boll's Modellbahn-Technik as this module can be rather challanging to construct. This I can say from experience since I etched the board myself and soldered the tiny pieces on myself.

All you would have to do then is follow the modification steps on either site for installing the module and start using it.

Yes the task is not for the beginner type. There are quite a few steps involved and quite the learning curve for me since I also had to program the unit with the proper firmware. The end result is well worth the effort in my opinion.

If you do decide to try the modification and run into a problem don't hesitate to ask for assistance, that is what we are here for.
