Philouzo Posted September 24, 2015 Share Posted September 24, 2015 I purchased a dcc ready A1 class Tornado and fitted a bachmann chip to it. When i tried to run it it wouldn't go without a little shove? once it's running it seem ok apart from when i try to run it at slow speed it just stops? once it has stopped i have to disconnect the power and leave for a few minutes before i can try and run it again!I took it to a local shop and they reset the chip back to factory settings and demonstrated it to me on a lay out in the shop, it ran perfectly.I got it back home and there is no difference?i've tried resetting the controller, everything is clean and contacts are good?Is my controller faulty?

Howbi Posted September 24, 2015 Share Posted September 24, 2015 @ Philouzo...If you are using the 36-553 decoder the manual states..." The default CV values are suitable for many motors. However there may be instability in motor performance when the Back EMF control is not matched to the requirements of the motor. If this is found then CV's 54 & 55 should be adjusted" Your problem is that the Select controller is not capable of addressing these CV's. You could try adjusting the Acceleration Control as detailed on page 8 of the Select Manual. HB Link to comment Share on other sites More sharing options...
Michael_A Posted September 24, 2015 Share Posted September 24, 2015 The Select is not NMRA compliant, so I suspect it's having issues with the Bachmann decoder. Assuming the loco runs OK on DC, unless you want to change your Select, I would try a Hornby decoder. I personnally no longer trust Bachmann decoders as I have also had issues wih them, even with an Eite, which is NMRA compliant Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 24, 2015 Share Posted September 24, 2015 Phil, a belated welcome to the forum. No need to address your problem, your solution is almost certaimly in the higher posts. Michael, have you tried CVs 54 and 55 adjustment? Many cases where this was necessary have been documented here. It's not just a rare case as the decoder manual implies.

Philouzo Posted September 25, 2015 Author Share Posted September 25, 2015 Thanks everyone, i've decided to send the Select to Hornby for a firmware upgrade as i was only on version 1.1, if this doesnt solve it i will try a Hornby chip Link to comment Share on other sites More sharing options...
tony_forward Posted September 25, 2015 Share Posted September 25, 2015 No one mentioned an obvious one... Visit your local model railway club... Someone there will have an NCE powecab which will do all the above, failing which purchase an elink/railmaster to control your locos ... The club option is likely to be beneficial in more than just that though! Link to comment Share on other sites More sharing options...
Philouzo Posted September 28, 2015 Author Share Posted September 28, 2015 I can't use the elink/railmaster cos i dont have a PC! do i need to purchase the NCE powercab? Link to comment Share on other sites More sharing options...
Yelrow Posted September 28, 2015 Share Posted September 28, 2015 PHILOUZo, hi, we are not allowed to recommend other than hornby on this forum. My solution, would be to purchase an Elite controller from ebay. This is a controller made by hornby, and will do everthing you need it to. In the fullness of time, it will also work with laptop. Many of us use these, and are very satisfied with them. john Link to comment Share on other sites More sharing options...
