ph54 Posted January 16, 2020 Share Posted January 16, 2020 Hi all, I am have problem with my Class 50 by it run perfectly with the sound off. And run perfectly with just the lights on, as soon as I press any other F button it start to miss behave. It shutters and runs the length of a R600 and then stops of a second or two. All the sound goes off and then it run perfectly again. I've cleaned all the wheels and contacts just can think what CV to change if any otherwise I'm stuck. The decoder is the Hornby R8123 TTS, any ideas welcome. Link to comment Share on other sites More sharing options...
Howbi Posted January 16, 2020 Share Posted January 16, 2020 Try changing CV150 to a value of 1.........this has resolved jerky running for many members...........HB Link to comment Share on other sites More sharing options...
ph54 Posted January 16, 2020 Author Share Posted January 16, 2020 Thanks so the reply, but I've change CV10 to 1 and CV150 to 1, from a YouTube video. still no change. Stumped Link to comment Share on other sites More sharing options...
Howbi Posted January 16, 2020 Share Posted January 16, 2020 I'm surprised to see you have changed CV10 to a value of 1 when the default is 128........this will have a dramatic effect on the "load" compensation (BEMF)........It would be well worth you just trying CV10 @ 128 and CV150 @1 and let us know how it goes............HB Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 16, 2020 Share Posted January 16, 2020 Failing any improvement from the Cv changes, may be a faulty decoder for return to Hornby under warranty. Link to comment Share on other sites More sharing options...
