AntipodeanHST Posted October 29, 2019 Share Posted October 29, 2019 I need help with a Hornby East Midlands HST R2948 (which was released DCC ready). A previous owner has DCC fitted the power car. It runs on my DC layout very poorly, so slow that almost not at all. I have other DCC fitted HST units which all run fine on my DC layout but not this one. Does anyone have any idea what may be the reason for this. I wondered if it was something to do with the wiring and opened the unit up. The maze of wires and electrical componentry inside left me very confused as I am not into DCC operations. As I am in NZ Hornby repair personel are rare specimens! Any thoughts.

ellocoloco Posted October 29, 2019 Share Posted October 29, 2019 Hi AntipodeanHST and welcome... This model should have an 8 pin DCC plug so replacing it with a blanking plug should be fairly simple - both units will need one. This does not have to be a Hornby blanking plug and these should be available locally in NZ. An other option would be to take it to a shop or friend with a DCC controller and get the decoders reset to factory standards - the CV settings from the previous owner may have been personalized.

AntipodeanHST Posted October 29, 2019 Author Share Posted October 29, 2019 Hi ellocoloco .... Thanks for your help and advice. I think you may be right in that the decoder has been set to prevent use on a DC system. So now, as I understand it, I need to remove the decoder and replace it with a blanking plug in both power and dummy car & thus solve the problem.

96RAF Posted October 30, 2019 Share Posted October 30, 2019 If you don’t have a blanking plug a simple wire loop across the associated socket pins will do. Link to comment Share on other sites More sharing options...
AntipodeanHST Posted October 30, 2019 Author Share Posted October 30, 2019 Thanks guys .... all good now. Have removed the decoders from the two cars and fitted a blanking plug in each and loco runs OK now. Link to comment Share on other sites More sharing options...
