GreatWesternFavourite Posted February 27, 2020 Share Posted February 27, 2020 Yesterday, I inherited a BR B17/6 "Grimsby Town" No.61650 from my Grandfather. It's a DCC Fitted version and as far as I can tell, never been used. I cannot get it to run. Now, I know that it's not recommended to run DCC on regular DC, but it should at least run. I opened the tender to inspect the DCC chip and noticed a Purple wire that wasn't connected at all. I don't know if this was my grandfather trying to fix it as he doesn't understand DCC, a factory error. I would like advice on this, thank you :) Link to comment Share on other sites More sharing options...
Ard Lochan Posted February 27, 2020 Share Posted February 27, 2020 The purple wire is for auxillary use so you can ignore it, The DCC chip is probably set to dissable DC running, So either remove it and fit a blanking plate or if you know someone with a DCC layout ask them to enable DC running.

walkingthedog Posted February 27, 2020 Share Posted February 27, 2020 There is absolutely nothing wrong with running DCC on DC. It's the other way round that is not a good idea. Perhaps DC running has been disabled. I believe the purple wire is often not used. Link to comment Share on other sites More sharing options...

96RAF Posted February 27, 2020 Share Posted February 27, 2020 If not used the purple wired should be capped against shorting In any case. Link to comment Share on other sites More sharing options...
ColinB Posted February 27, 2020 Share Posted February 27, 2020 The purple wire is a function output, I use it sometimes for smokebox glow or cab lights. Yes, it has to insulated, I found from other users nail varnish works well. Link to comment Share on other sites More sharing options...
