Hi there!

I have a question regarding this decoder. I have bought one to replace the one from my Marklin 37023. I have no questions where to solder the wires except one, the brown who connects to the wheels of the tender. The decoder have one spot identified as GND (suppose is ground). Is this the spot where I have to solder this wire? The rest of the wires are all identified, and it's a question of following the manual diagram.

Any help would be aprecciated!

Miguel

Hi Miguel,

If you have a multimeter, you should be able to verify if that is a chassis ground. Measure between that (GND) ground contsct and the chassis & axles.
Ideally you should have 0 ohms resistance, but expect some small amount of resistance. It pays to zero your meter first, that is put the two probes together and see what the resistance is, as not all meter's read true 0 ohms.

Cheers,
Brian.

Hi Miguel,

I recently installed this same decoder, and the wires that are fixed to the decoder retainer (circuit board) are the only wires that need be connected to motor, tender wheels and lights.
There is no need to solder to the decoder or circuit board.

Thanks for the answers! (I Am Miguel different Login)

Im not sure if i understand. On the original configuration, there was a brown wire coming from the tender wheels to the old circuit board. This brown wire was independent from the other brown wire coming of the locomotive body. I don't know what is the spot to solder on this wire on the new circuit board, or if I must join the two brown wires, the one from the tender and the one from the locomotive.

Sorry, but this is my first installation, not really a veteran on this matter BigGrin. I will try Brian suggestion too!

Thanks

Miguel

Hi Miguel,

OK, join the old brown wire from the tender wheels to the new brown wire coming from the decoder/circuit board.

My loco was a 34157, so don't know if exactly the same. But I got rid of ALL the old wires, and just followed the Marklin instructions on where the new wires go.

You can email or PM me if you need other details.

regards

Miguel, What you find sometimes, especially with tender locos, there are 2 brown wires (ground) so the tender wheels add to contact to the track, sometimes this wire is transfered from the tender to the locos motorshield top screw and an other wire from the decoder is also soldered on the same spot.
Yes you can solder them together and it will improve the current pickup from your tender wheels or axles.

I have another question, how on earth do I remove the sockets for the lightbulbs? It is a question of pressure?

Thanks for the help!

Hi there!

I have a little problem with one of my locos. I have installed a 60945 decoder on a Br53 (37023). All is fine except one thing, sometimes (it seems a random behaviour) when the loco have the sounds on and I invert travel direction does not move. It makes the steam discharge sound, and then makes nothing. It continues with all sounds and all of the functions ok, but it does not move in any direction. To make it move again, I have to press the stop button on my Central Station 2 twice and, the loco resumes normal operation.
I have reset the decoder to factory default, but the loco does the same thing eventually.

Any suggestions?

Regards

Miguel Nascimento
