Electrostar123 Posted December 7, 2019 Share Posted December 7, 2019 I bought a ‘brand new’ Hornby East Midlands HST pack a while back. It runs ok on DC, albeit a little jerky, but on DCC operation the motor cuts out every time I get above a speed step 8 and the train comes to an abrupt halt. It’s not shorting out as the directional lights stay on the whole time. I have tried both the standard Hornby decoder it came fitted with (R8249)and a Hornby Valenta TTS decoder and the same thing keeps happening so it must be the train. Any ideas anyone? Thanks in advance. Link to comment Share on other sites More sharing options...
jane1707819582 Posted December 8, 2019 Share Posted December 8, 2019 The first thing to do is remove the erratic movement in DC mode .dcc will only amplify any faults . if not already done so gently Run in the loco for a hour in DC . Link to comment Share on other sites More sharing options...
96RAF Posted December 8, 2019 Share Posted December 8, 2019 With the TTS decoder fitted does the sound cut out along with the motor. If not then it points to a motor fault, possibly any suppression kit going south or the motor itself. Further checks required. Link to comment Share on other sites More sharing options...
Electrostar123 Posted December 8, 2019 Author Share Posted December 8, 2019 Here I should a video I uploaded of the issue: "> I also read this in the decoder manual that came with the train: ‘The current for all the decoder outputs is supplied by an internal rectifier with a maximum current of 1 Amp and the rated continuous current is 500mA.The sum of all currents to the motor and the function outputs should not exceed 500mA at normal continuous operation and cannot exceed 1 Amp. If the motor current exceeds 500mA the decoder will automatically cut off power to the motor.’ Could that be the problem? Do I need to fit a decoder with a higher amp limit?
