Stormbringer Posted September 21, 2019 Share Posted September 21, 2019 Hi all, I've just purchased D6916 as dcc fitted via ebay, when I opened the loco up I discovered that a dark blue wire from the decoder was flapping in the breeze as per the attached picture. My question is should it be doing so? Or should it be attached somewhere and if so where? TIA Pete Link to post Share on other sites More sharing options...

Unfortunately the camera on my tablet is crap and for some reason I can't upload pics from my phone. Thank you for your reply.

RMweb Gold pheaton Posted September 21, 2019 RMweb Gold Share Posted September 21, 2019 (edited) Don't worry about the purple wire just make sure the end is insulated and you will be fine, the purple wire is normally used for extra functions like powering a smoke generator.

Phil S Posted September 23, 2019 Share Posted September 23, 2019 IF you wanted to modify the basic setup so that the tail lights were independent eg off when hauling coaches/wagons in the UK - this would use 4 functions - and the green and violet wires would come into use - by default on a SILENT decoder as F1 and f2 in many cases* (with white and yellow as fwd and rev directional lighting by default... for example disconnecting the tail lights from operating on F0 with directional headlights .. and changing them to operate from green and violet instead ( you MIGHT be able to use existing series resisitors with LED lights, but otherwise simply use another resistor in series with each fof the green and violet wires - abput 1k - 2k2 is likely to be correct - depending on your chosen/existing LEDs ...modern LEDs are much brighter than oldr types! (very different and unchangeable number(s) on TTS decoders - but the same colour options 1 Link to post Share on other sites More sharing options...
