SimulationNetwork Posted August 31, 2020 Share Posted August 31, 2020 Hi all! I have a Bachmann Class 350 that has a 21-pin DCC decoder fitted to it. Strangely enough - it works on DC. No issues there. However... on DCC power the coach automatically jolts between a slow and fast speed. I've tried registering the decoder on a seprate piece of track with my Hornby Select. No luck from that... Any help would be great. Cheers, Luke Link to post Share on other sites More sharing options...
London Southwark Posted August 31, 2020 Share Posted August 31, 2020 Try another decoder I had a issue like that I stripped the loco down and after all that it turned out the chip was defective. Link to post Share on other sites More sharing options...
letterspider Posted August 31, 2020 Share Posted August 31, 2020 Before you toss it away...reset the decoder. Reprogram the start voltage...I think it is Cv 03. You will need to check through the other forums as this is explained better than I can. 1 Link to post Share on other sites More sharing options...
Ron Ron Ron Posted August 31, 2020 Share Posted August 31, 2020 It would be more appropriate to post this in the "DCC Help & Questions" section. Link to post Share on other sites More sharing options...
