Yelrow Posted February 20, 2019 Share Posted February 20, 2019 Great, Barry, well done. I still think mark ought to know, as the next owner, may not be as Technical Thank heavens, i dont own one. It would have been perhaps beyond my simple brain. It seems wrong that stocks still on shelves with this known fault. Link to comment Share on other sites More sharing options...
Bulleidboy Posted February 20, 2019 Share Posted February 20, 2019 Hi John - Reading through the thread again, it would appear that Hornby were aware there was a problem with "some" not all Adams Radials, and did repair/replace(?) those that were sent back. Mine has been sitting in the cupboard since I bought it in 2016 - although I think I did run it for a short time when I first got it. Having said that, from what has been said, it should have fried the decoder straight away - but it didn't. Barry Link to comment Share on other sites More sharing options...
Bulleidboy Posted February 20, 2019 Share Posted February 20, 2019 I think I spoke to soon! On the rolling-road, under DCC power and with body off, it ran beautifully. smooth and the slow running was very impressive. I put the body back on, placed it on the track, and it's a nightmare, to say it runs jerkily is an understatement. So body will be off later, and some investigating to do.

Bulleidboy Posted February 24, 2019 Share Posted February 24, 2019 I couldn't find anything binding, but it's virtually a non-runner with the body on. Will try again without screwing the body on. Link to comment Share on other sites More sharing options...
walkingthedog Posted February 24, 2019 Share Posted February 24, 2019 When you tighten the screws is it distorting the chassis? Link to comment Share on other sites More sharing options...
96RAF Posted February 24, 2019 Share Posted February 24, 2019 ...Or is it pressing the decoder onto something metal or shorting a wire. What about the purple flying lead on the R8249, is it capped and stowed along with any wires cropped for a hard wire installation. I wish every model came with a clear plastic body or an X-ray app for your phone. Link to comment Share on other sites More sharing options...
Bulleidboy Posted February 24, 2019 Share Posted February 24, 2019 Rob/Brian - I hadn't screwed the body down hard - usually once I feel the resistance when replacing the screws I stop. The TCS decoder is just a plug-in, so no wires. I did try pressing down on the decoder when it was on the rolling-road, but everything was fine. There is no capacitor to remove. I'll try again without replacing the screws. Barry Link to comment Share on other sites More sharing options...
96RAF Posted February 25, 2019 Share Posted February 25, 2019 Sorry BB I missread an earlier post that was talking to R8249.I wonder if the body is just displacing the direct plug decoder enough to affect it, but more likely its a metal contact problem, maybe under the socket.

Bulleidboy Posted February 26, 2019 Share Posted February 26, 2019 With the body back on, but not screwed on, the loco runs. There is no movement when the body is in place, but I will check whether the body is pushing down on the decoder. Link to comment Share on other sites More sharing options...
