perfectionist Posted January 13, 2018 Share Posted January 13, 2018 Bought Gadwell tts 2 yearsw ago. Ran to test all well. Re boxed and not used again due to relocating layout. Put on new layout again today. ran fine, short circuited on 3 way point, now dead. Any ideas ladies and gentlemen. Using elink. Link to comment Share on other sites More sharing options...
WilliamDavid Posted January 13, 2018 Share Posted January 13, 2018 My TTS locos have shorted the tracks on a regular basis, causing the Elink/Elite to cut out. Never damaged the chip, and I can't see why it should.Maybe someone can advise me if I'm wrong. Link to comment Share on other sites More sharing options...

Chrissaf Posted January 13, 2018 Share Posted January 13, 2018 The short circuit may have corrupted the decoder configuration. Put the loco on the eLink programming track and try reading the CVs. Look at CV1 to see what DCC Address it shows. If it is not showing the address you expect, then try resetting the decoder to factory default [write 8 to CV8], then reconfigure the address you require before trying it again on the main track. If you can't read any CVs or you are not getting the values you expect, then the decoder may have been permanently damaged by the high spike voltages generated by the short..The adverse affect of 'short circuits' on DCC decoders can be mitigated if you fit a 'Snubber' to your DCC power distribution..The linked page above also explains the theory of short circuits and their potential effect on decoders. Not everybody will necessarily be affected by short circuits, many are, but some are not. It all depends on the specifics of one's layout and wiring.

perfectionist Posted January 13, 2018 Author Share Posted January 13, 2018 Update. Deleted Loco from my list. Programmed back in as though just bought, including re entering change of loco id. Saved. hey presto Gadwell now alive and kicking. Link to comment Share on other sites More sharing options...
Chrissaf Posted January 13, 2018 Share Posted January 13, 2018 That fix infers that the short circuit corrupted the DCC address in the decoder as I suggested in my earlier reply. Still worthwhile considering the fitting of a 'snubber' though, to offer some future protection against it happening again. Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 13, 2018 Share Posted January 13, 2018 If it happens again, check if it has reverted to address 03. I suspect that was all that was wrong and you fixed it with your reprogramming of the address, nothing to do with removing and reentering the loco in your list. WD, now we’ve solved the OP’s problem, I think you will find yours is quite different and likely to be the wheel back-to-backs being out. Link to comment Share on other sites More sharing options...
