Hi there,
I have two old Delta sets with steam locomotives, sets 2916 and 2964, both sets were purchased during the early 1990's.
Both steam locomotives have the digital address 78.
These Delta decoders do NOT have the DIP switches, so I can not just simply reset the dip switch.
Is there a way to program one of those to a different digital address (75) using my old 6021 control unit ?
Otherwise will I just have to live with it and make sure that both locomotives are not running at the same time ?
Both of these locomotives are fairly cheap, so I really do not want to go through the expense of buying a new decoder, besides, I have no clue how to do that.
Thanks for the help
Tim

Tim Yes you can. I don't have the instructions handy for doing this with a 6021, but it is certainly possible to do it. It is a bit of a hassle though, if you know someone with an ms2 or cs it will be easier to use that.

There are no marklin dealers or marklin users I know off in this part of Georgia. I am a lonely wolf here :)

I saw those as well, but my soldering techniques are just not good enough for those kind of details.
My chances of burning that decoder when doing that are very close to 100%.

ok, so you may have to mail one of them to someone and have them do the soldering, or install a new decoder |

It would be nice to know exactly which decoders are mounted, and if possible, find the instruction manuals for them If soldering is needed, it must be possible to find someone to help you; but instead of soldering, it could also be de-soldering / removing a connection, which then could be done with a sharp knife, instead of a soldering iron  Per.

Yes, which is why I used the word 'usually' in reference to DIP switches - having in the back of my mind the fact that some decoder addresses are programmed via a solder bridge.

Here is a picture of the locomotive and the decoder. Now you can see why I am not willing to spend any money on it, it is cheaper to just replace the unit.   Thanks for all the replies. Tim

I honestly do not know why one of the pictures turned around.
I did them both the same way.

Thanks for all the replies. Tim Right, that looks like the loco from the 2915 start set, or similar set. You can see the solder jumper points in the top right hand of the second picture. Personally I would put solder blobs on the three remaining contacts (you can see the top one has solder on it) and that would give the loco an address of 80.

or try one of the product that comes in a tube that conducts electricity. Just add a blob between the pads as needed.

Hi there,
I bought myself a little soldering iron at the Home Depot.
I bridged the 2nd contact from the top without burning anything else (but it was close).
Now the little steam locomotive is chugging happily along on digital address 72 without any issues.
My original diesel 33744, which was at a digital address of 72, has dip switches which I could reset easily.
So now I am good to go with all my locomotives.
On to the next project.
Thanks for all the help in resolving this issue.
Tim

Tim Oh great. welcome to the world of tweaking your items ...  Glad you had success.

Right! There are also pens with conductive ink for around $7. Or conductive paint, like any other Humbrol/Airfix can. Not long ago I bought a soldering iron for around $6. Incredibly cheap. With a real wooden(!) handle. It´s really bad of course, but could be used to place a blop over the pads... |
