John Boy Posted May 21, 2019 Share Posted May 21, 2019 I have purchased a used, but looks unused, Little Loco Class 15 DC version. I emailed Little Loco Co to purchase an appropriate DCC decoder, without response. Rather than settle for a compromise, I rang round the Little loco Co stockists, and was pleased to secure one for £100. The decoder was promptly supplied with full documentation. On fitting and testing the decoder, all sounds are correct. The loco runs backwards when I think it should run forwards, OK easily fixed with CV change. However the brake function does not work correctly as CVs 3&4 are both set to 10, CV 349 set to 6. Before I start to experiment by changing these CVs, does anyone know what the correct values should be? There is a further problem, If all the marker lights are turned on , not only are they not all in the specified positions, but two are on at one end and two are on at the other end, they do however change ends when the loco direction is changed. With the current problems at Little Loco Co, I am loathed to return the chip to the supplier, as I probably will not be able to get another, and the sound functions are good. Any advice will help before I attempt to correct the faults. Link to post Share on other sites More sharing options...

John Boy Posted May 22, 2019 Author Share Posted May 22, 2019 Gentlemen, Thank you for your responses, I have contacted Paul Chetter, and await a reply. Link to post Share on other sites More sharing options...
Daveloco1 Posted May 22, 2019 Share Posted May 22, 2019 Hi John Boy I had similar issues with my Class 15 which was purchased with a decoder fitted. Had a lot of problems with lights not going on/off as instructions. Turns out it was a older decoder, Steve from Little Loco offered to change it for free but I believe there was a 'fix' on Little Loco's web page so I used that and all worked perfectly. I have 'tweaked' it a bit more when Paul gave a set of CV's to change so that a each function button set up a different headlight 'headcode' arrangement for say, light engine or fitted goods etc. It was quite a long set of CV's to amend but works brilliantly. Certainly Pauls the man. I doubt you will get any reply from Steve as Little Loco Company is up for sale, see their trade thread on here.

pauliebanger Posted May 22, 2019 Share Posted May 22, 2019 John, I'll answer your PM in more detail shortly. To eliminate all other reasons than someone has 'adjusted' some CVs, first thing to do would be a decoder reset. Use CV8 = 8 which will reset all CVs to that supplied originally. This is not a reset to factory defaults. Running the in the wrong direction and lamps illuminating inappropriately is not a disaster, it can all besolved by CV changes. At least you know that the motor and all LEDs are wired and functional. Best regards, Paul 2 Link to post Share on other sites More sharing options...
Fastdax Posted May 22, 2019 Share Posted May 22, 2019 I also bought a refurb LLC Class 15 as DC. Do I need a special decoder from LLC or its distributors, or will an ordinary Zimo MX645PluX22 with Paul's Activedrive sounds from Digitrains do the job? Thanks Link to post Share on other sites More sharing options...
John Boy Posted May 22, 2019 Author Share Posted May 22, 2019 Duncan, I purchased my decoder from Trains4U who are a Little Loco Stockist, It was the only one they has in stock. However, they were the first one I rang from the list of stockists on the little loco website which is still operating. If you bought your refurbished loco from the Little Loco Ebay site, you may be able to contact Steve through " contact the seller". I did contact Steve through this route, and he said Little Loco were out of stock but may be getting further stock. May first call would be to Digitrains.

John Boy Posted May 22, 2019 Author Share Posted May 22, 2019 Paul, I have reset the decoder. CVs 3&4 are now reasonable values and the loco drives as I would expect. The marker lights are still adrift F 20= Front lower left F 21= rear top F 22= rear lower right F 23=front lower centre All lights respond to change of direction. Forwards being cab end leading. Thanks for your help John 1 Link to post Share on other sites More sharing options...
Daveloco1 Posted May 23, 2019 Share Posted May 23, 2019 John It looks very much like the way mine operated when I first purchased it with an early decoder. At one time there was a fix on Little Loco Company's web site but I'm having trouble getting on that. I'll see if I have still got the cv's re-set numbers this evening if that helps.

Ian, It's an indication that the decoder is from the early batch, but the real issue is that the factory changed the wiring at the production stage without telling us. I'll post the 'correction CVs' shortly. Best regards, Paul 1 Link to post Share on other sites More sharing options...
pauliebanger Posted May 23, 2019 Share Posted May 23, 2019 (edited) Please amend the CVs listed below to the values shown. This should correct the direction of travel and the incorrect lamp illumination. CV29 = 7 and Best regards, Paul Edited May 23, 2019 by pauliebanger 1 Link to post Share on other sites More sharing options...

I subsequently up-rated the function buttons as your instruction to give different headcode light arrangement for class of train which is brilliant!

pauliebanger Posted May 23, 2019 Share Posted May 23, 2019 Dave, You're quite right, I've clipped the list too short. CV458 = 7 should also be included, otherwise, the cab light will only illuminate in one diection only. Sorry to anyone if that caused confusion. Well spotted, Dave.

John Boy Posted May 23, 2019 Author Share Posted May 23, 2019 Paul, Thanks for the amended list of CVs. I will input the values and confirm the operation. Many thanks for your help. John Link to post Share on other sites More sharing options...
John Boy Posted May 24, 2019 Author Share Posted May 24, 2019 Paul, I have input the CVs, and the loco now performs perfectly. Thanks again for your help. John Link to post Share on other sites More sharing options...
