Hello.
Some months after my first experiences of Marklin products. I decided to buy a turntable 74860.
I was very careful to build the cradle. (level, power supply, etc.).
From the CS3,I ran a search for mfx articles following the notice instructions.
The result was several Right switches corresponding at each function of the turntable. But the bridge never turn.
I returned the turntable to the seller which ship the turntable to Marklin.
I received the turntable and I started the installation again.
But there is no change. The seller told me that all was OK at his workshop
Do some one know how to process for a casual use?

Of course I saw all these video several times.and I contacted some forum members across Internet.
But when I am in front of my CS3 it is different.
Sometimes I Cant Initialize (no screen for it)
Sometimes I succed in initialization but the Turntable does not turn.
It seems to me that the decoder cant drive no more the motor.

Hello Alain

Disclaimer: I don't have this truntable (rather a 7286 with a DSD2010 set of 2 decoders, with sound and 4 signals). I have a CS3 (60226).

Here is my 7286 TT in 100% automatic operation, using Rocrail https://www.youtube.com/watch?v=SzgCvLKjq8I

Back to your TT
One possibility is to start from zero the electronic installation (not the mechanical one):
- verify that the latch is not engaged? (Can you ratate the TT by gently turning it by hand? NO BRUTE FORCE.
- the 74862 being an MFX, DCC and MM2 unit, IMO it is best to operate it from MFX. Are you using MFX?
- chances are you unit is already registered as MFX. IS it not? In that case select the MOFIFIER tab and then select CHERCHER ARTICLE MFX
As you know there is a German video about the whole installation process here

- 0:40 into the video, this is about searching the MFX item (CHERCHER ARTICLE MFX) and then to select the address range (normally 225 but you may pick another address
- 1:33 into the video, the MFX registration is finished (But NOT the TT initialisation)
- 4:12 into the video, the TT initialisation can start (the TT will rotate from its present track (assumed to be track 1) and will take note of all places where an access track is installed
- 6:20 into the video, the initialisation is finished and the CS3 now shows where the access tracks are identified.

You know all this so now, what can go wrong?
- the TT is not MFX recognized: Select CHERCHER ARTICLE MFX
- the TT is already registered by the CS3. Can you rerun the initialisation like in the video above (4:12 into it)?
- the decoder is it KAPUTT? can it register in MFX, can it be initialized by selecting the CV and writing 8 into the CV 8?)
- are other fonctions working (sound, light, etc) ?
- can you UNLOCK the TT (command the servo motor which lock / unlock the TT See page 19 "Déverrouillage/Verrouillage de la plate-forme"?

Here is the user's manual of the 74862 https://static.maerklin....09dc6f30c31686554821.pdf

So there are many questions, sorry for this.

Other issues that may happen is the detection small pieces may jam the TT if they become loose.
The TT has a mechanical drive based on a big wheel and worm gear with a clutch, so normally, the TT does not get damaged when stuck by any cause (locking tab engaged or the access track detection small pieces). The key is to first UNLOCK the TT and then move it gently to see if there is something in the way.
Just for you to know here is the 74861 once opened

Many times before my purchase I saw all the videos Youtube upon this turntable. When I received it, as I said above, All was ok.
But as many Marklin products. After few days, it run no more. Why? I do not know. One time, someone told me that I need to run the wifi for updating the item. Someone else inform me that micro cuts will damage the system. My culture of Model railway is not so ambitious that Marklin try to implement objects as Turntable 74862. I was born too early.

I bought it in july 2023. The first day Ireceived it. All was ok. Two days after it run no more as many items Marklin. The seller proposed to return the TT to him.
I received the TT back about the 15 of september. The seller told me that I have nothing to pay. The reparation was under waranty......
I tried to use it but it was the same problem. I phoned a new time to the seller to inform him that the reparation were inefficient. I proposed to ship back the TT with a refund from him. The seller then told me that too many days have passed since the purchase.
Here's about the warranty.
concerning the ship to MarklinI have a bad experience with a CS3 in 2020. I repeate. It was a mistake for me to implement Marklin.
Regards.
Alain

Thank you for these few reassuring words.But maybe you are more patient than me.I am aware that Marklin remains good material.
With electronics and age, it's less easy to find where a malfunction is coming from.
Thank you.
Alain

I have been looking thru the dutch 3 rail forum in the las few months , numerous comments regarding the new turntables problems making a worthy read on a cold wet night .
