Barry-1228798 Posted January 16, 2023 Share Posted January 16, 2023 Hornby R3827 LNER Hitachi Class 800/1 Azuma Set 800 104 Celebrating Scotland Train Pack - Era 11Hey Guys,I’ve got a problem with slow speed running, accelerating and decelerating. The brand new model judders badly and the motor makes some terrible noises.It’s running with a Hornby R8249 Decoder and Hornby Select Controller. All CV’s are set as per the manufacturer. I’ve tried backing the bEMF down but this doesn’t seem to help. I’ve also tried adjusting the acceleration, deceleration and speed step parameters but no joy. Here’s a video..https://share.icloud.com/photos/02eBa9wCEHO5Rz5-06Vx85pNQAnybody got any ideas, its driving me nuts! Any advice, much appreciated! Barry.

rpjallan Posted January 17, 2023 Share Posted January 17, 2023 Did you fit the decoder or did it come already fitted? What controller are you using? Sounds to me like a capacitor problem. Did you remove the capacitor on the motor when you fitted the decoder?Rob Mod note - OP says he has a Select controller. Link to comment Share on other sites More sharing options...
96RAF Posted January 17, 2023 Share Posted January 17, 2023 As it is new I would contact Hornby Customer Services for a warranty repair before messing about with it, especially cutting out capacitors.i would however check any power track or power clips feeding your track for a capacitor which should be removed.

Brew Man Posted January 17, 2023 Share Posted January 17, 2023 Note to Mods. This thread should perhaps be moved to the DCC forum as it appears to relate to decoder issues. Link to comment Share on other sites More sharing options...
