QUOTE (Keith Underwood @ 8 Jun 2008, 15:41) <{POST_SNAPBACK}>Hi everyone
Has anyone had any problems with Bachmann Deltics or Bachmann A1's (both of the 8-pin socket type). Both my locos were running fine but suddenly they do not respond on the track. They are fitted with TCS MC2 decoders (my system is Gaugemaster Prodigy Advance).
I have tried putting them on the program track and reading back the address, which is fine on both. I have put the "blanking plug" back in and run them on a DC test track, which is fine (nice runners in fact). The wheels and track are clean and all other DCC locos are running OK. I have even tried swapping for a couple of spare decoders (Lenz and Bachmann) and, while they still accept programming on the program track and read back their correct addresses, they do not respond on the main track!
I could try hard-wiring the decoders in and by-pass the socket, but I don't know if this will solve the problem, whatever it is!
Any ideas? Or has anyone had a similar thing happen and resolved it?
Thanks
Keith

My next action would be to either deliberately go through the actions of address etc on the programming track, or I would do a factory reset and start again (cv 8 set to 8. It may read 153 as that is TCS's ID number. or on the list I have it also says cv 30 set to 2)
The decoders come with information on the various settings for cv's. I am a novice but have found patience, and trial and error and using this forum gets me there.
Hope this helps
Paul

It had the expected result of setting back to code "0003" when I read the address again, but the loco still did not respond to this address on the main track. But I will keep trying and let you know if I find the answer.

Hmmm, It may be a 'fluke' that both the A1 and Deltic have apparently developed the same fault. The fact that you replaced the decoders with a Lenz and Bachmann (which I assume you know work) and still got no result...yet they read suggests that may be there is either an open circuit to the motor or a short. Do the lights work? but not the motor? If it were a short then it would probably cause the decoder to cut out anyway as its intended to. John suggestion of removing the capacitor, and I have seen other articles on this site that suggest that...why it would work at first and then not later I don't have the knowledge to say. I've got an A1 and an odd decoder so maybe I'll go and have a play to see what happens.
