I doubt it is the motor but I assume if I strip out the decoder, I could apply a voltage to see if it runs. I doubt if I can find a UK dealer who could fix it so I'd like to have a go and fix it myself. If I wish to replace the decoder chip, where should I look to get a new chip and the necessarry instructions? I there a particular chip/make I'd need?

It is impractical to replace the chips on a decoder, especially the microprocessor chip as there is no way to reprogram it. Just what is the catalogue number of this loco? Whereabouts in the UK are you situated?

I will have a look and see and work out a price.

I'm no electrician but: I'm getting a continuity sound from a couple of large resistors at the motor end and another couple give a reading but no sound. Touching anywhere on what I think is the decoder (sitting vertically and at right angles to the track/wheels) gives not sound or reading.

The locomotive are fantasy model. Never seen this model before made of Märklin. Huh? It is not a Delta decoder, it is an fx decoder. While they may be made to a price this doesn't mean they will have a short service life. yet another pronouncement from someone who hasn't worked inside the electronics industry. The model may be a 'fantasy' model, there were a small handful of these using asian manufactured chassis with oversized wheels, and fitted with the V60 body, and another steam loco with a 3000 like body. They were mentioned with this forum some years back when they were current, so you will have seen mention of them here, even if you haven't sighted a physical example.

In the manual of the locomotive it does only have one adress and it´s 72. Fx decoder does not have this.

Maybe you should read the manual again................ • Recognition of the mode of operation: automatic. • Addresses that can be set: 01 – 80 • Address set at the factory: 72 • Headlights for the locomotive. They can be turned on and off in digital operation • Adjustable acceleration/braking delay. • Adjustable maximum speed. • Setting the locomotive parameters (address, acceleration/ braking delay, maximum speed): with the Control Unit, Mobile Station, Central Station https://static.maerklin....18e76db74f1434542086.pdf This is clearly a FX decoder Per.

Assumed dead 70 % (guessing) Model number: 29108 Decoder to replace? Yes and probably with a DCC one for N scale. Control unit used? CS3 So you can install a multi protocol decoder without problems, any brand is fine. HTH

Does the CS3 have the possibility to find the address of a decoder so that you can see if it was changed and you don't remember ?

The thing is dead - no lights respond - nothing reacts - I've tried many id addresses as outlined here above and nothing. I'm 90% positive it need a new decoder.

HTH You are helping me as you are confirming what a lot there is to know about these models as well as confirming what I tried . I'm not sure though why I might need an N scale decoder for a H0 scale loco?

The decoder dimensions are 22.5mm long (when i trim the ends of the heat shrink), and 17.5mm wide (over the heat shrink). If things are really tight then the heat shrink can be removed.

The 60760 decoder is the same PCB size as the original decoder, but wouldn't clip into the plastic clip because the placement of components is different, so a wee rearrangement was needed, but eventually everything was wired up properly and the body fitted.

It was a privilege talking to and watching a truly skilled man like Alan isolate and repair my diesel locomotive. It also made me aware of just how much I would have struggled if I had attempted it myself. A real education.
