dgp1957 Posted June 1, 2022 Share Posted June 1, 2022 Hi folks, yesterday I installed a Hornby TTS sound chip into Hornby A3 loco . Everything worked fine until the loco derailed. Since then everytine I put loco with chip on track the motor runs with no control. I have tried resetting the chip but no luck I have to keep the loco body off the track whilst trying to reprogramme as as soon as I connect the chip the motor starts. Is the chip knackered or is there a way round this. I am using an NCE Powercab. Link to post Share on other sites More sharing options...
WIMorrison Posted June 1, 2022 Share Posted June 1, 2022 I would suggest that you place it on the programming track and reset the decoder back to defaults as a first step. Link to post Share on other sites More sharing options...
dgp1957 Posted June 1, 2022 Author Share Posted June 1, 2022 Hi I have done that Iain, I have to make sure the loco body is not in the rails, but the tender is. As the motor runs as soon as decoder is connected . It didn't make a difference, it powers the motor as soon as fitted, with no control at all.
