RMweb Premium glasmonkey Posted December 18, 2016 RMweb Premium Share Posted December 18, 2016 Hi everyone I'm very new to DCC. I have a TTS 47 and thought I put a better speaker in it, which I did and it sounded great until the two speaker wires touched each other - a burning smell then no sound, so I assume that's the end of that decoder and nothing can be done?! Thanks. Rob Link to post Share on other sites More sharing options...
Phil S Posted December 18, 2016 Share Posted December 18, 2016 Next year, many of the TTS modules will become available as a separate part: 40GBP (36GBP quoted by Hattons) For future problem avoidance: heat shrink sleeving is available from places like Maplins or Ebay in various sizes - suited to protecting joined wires etc against accidental contact. Another smoke preventive measure suited to some of the newer Hornby Motor bogies is to apply some insulating tape or small piece of plasticard over the exposed terminals on the side of the motor bogie ... which are adjacent to the magnets... such that any loose magnetic item on the track is attracted, and immediately shorts the motor, thus destroying the decoder (that was a different make of sound decoder in my case 8-( ) Link to post Share on other sites More sharing options...

RMweb Premium newbryford Posted December 18, 2016 RMweb Premium Share Posted December 18, 2016 I wouldnt imagine the speaker wires would have caused the decoder to burnout? It would certainly take out the amplifier circuits for the speaker. Although the decoder may still have motor control - as the OP says - no sound, but hasn't said if the loco has stopped. (I've learnt the hard way in the past about keeping speaker wires away from each other and live rails......... - yet the motor circuits still worked) Cheers, Mick Link to post Share on other sites More sharing options...

It only happened because I was testing everything before I put it all back in the loco and sausage fingers!! Rob Link to post Share on other sites More sharing options...
