Sorry if Im breaking any rules here. New to the forum. Took up my old marklin and did my first digital conversion as "corona lockdown" project.

I had an old 3060 Santa Fe which was brought used. I switched the motor with a 60943. Stripped everything else except for the light bulb. The show was very used, so I replaced with another (ot cerain which type). Used a mfx decoder 60760 according to the schematics. Unfortunately the loc is not recognised by te mobile station and the ligtbulb is continously blinking. Can anyone point a specific error here or is just due poor soldering somewhere.

First error: 60760 is not mfx.
Not sure where the blinking could come from. Maybe share some photos.

Are orange and grey soldered to the same spot? That would be wrong.
Orange is only used for light bulbs that are not connected to the loco frame. As far as I can tell orange should not be used with that loco.

The default address of 60760 is 78. Enter it manually to your MS and see whether you can make the loco move.

Concur with H0 above. I cannot quite see where the yellow cable is soldered to; it and the grey should go to the light bulb.

And don't turn on the lights when orange and grey or orange and yellow are soldered together.

Hello

Yes, the orange wire should not be soldered anywhere, because the lights powered by the yellow and grey wires are grounded by the chassis.
So unsolder the orange wire and ensure that the wire end is not touching anything else, preferably put some insulation tape over the tip.

The 60760 does not automatically register itself on your system.
You have to go to the menu option where you manually create a new loco, and you describe which loco it will be.
The 60760 comes by default with address 78, and this address number can be changed with the menu option to whichever address number you prefer.

Thanks alot to everyone for the advice and input. Highly appreciated.

I did as suggested and now the loc moves BigGrin . Nicely spotted with the orange. I followed the schematics so probably my set-up is different.

Only issue is that the light is not working, however i havent checked the functions in the set-up yet.

I will see if this can be done for some of my older locs as well - would be a shame to not have them on the tracks again.

If you burnt the grey output then maybe give the yellow output a try.

The front light is either connected to grey and orange without connection to the frame. Or it is connected to grey and frame without connection to orange. There is a warning not to connect orange to the frame.
There is no warning not to connect orange to grey, but still this can be harmful.

Here are two proper installs in 3060 Santa Fe F7s. One is with the 60906 decoder that retains the field wound motor. Second picture is with the 60972 decoder along with the 5 pole DCM style motor that replaces the SFCM motor that was originally in the model. The extra coiled wires in that model are for an additional light function I plan to add here soon. The upgraded motor one runs better obviously, with the old field wound flat communtator motor needing to run faster and it slows down and speeds up on its own, just like running on analog control. But that was the design of that decoder set up.
