Can I just bypass this and wire a decoder to the motor? Ian could you please gives us a little more info. was the loco running ok on DC or DCC? Is the item in the photo the DCC blanking pub that plugs into the locos main PCB? and why do you think it needs replacing? Would not recommend wiring decoder directly to a Murphy Model loco. The onboard PCB has all the logic for controlling the lights, etc, which you'd lose. Are any of the pins sticking up from the 21pin plug on the main PCB bent? If there is no apparent damage to the main PCB on top of the loco chassis all you need to do is install a 21pin decoder and test it as ADDRESS 3 until you re-program the loco address. Would you prefer to run the loco on DC or DCC? Edited February 29, 2020 by Noel 1 Quote Link to comment Share on other sites More sharing options...
0 IANG Posted February 29, 2020 Author Share Posted February 29, 2020 It was running on dc and I was just testing it but I noticed there was another loco on the track so I pulled it up and it hadn't been working since that. So I gave it to a guy who has a electrical shop he was checking it over with volt meter trying to fault find he thought it might have been a short circuit and he came back with the decoder socket isnt working from what I understood. I have asked him again what was wrong to get better idea. That's photo he sent me Quote Link to comment Share on other sites More sharing options...
0 enniscorthyman Posted February 29, 2020 Share Posted February 29, 2020 That looks like the blanking plate that covers the 21 pins when the loco is running dc. Quote Link to comment Share on other sites More sharing options...
0 IANG Posted March 1, 2020 Author Share Posted March 1, 2020 Is it possible for these to short out ? Quote Link to comment Share on other sites More sharing options...
0 WRENNEIRE Posted March 1, 2020 Share Posted March 1, 2020 Very unusual Ian, never had any trouble with them unless it has been installed incorrectly Where are you based? I have some spare blanking plates that you could try Or can you stick the blanking plate in another loco to see if it is OK? Quote Link to comment Share on other sites More sharing options...
0 Noel Posted March 1, 2020 Share Posted March 1, 2020 6 hours ago, IANG said: Is it possible for these to short out ? Very unlikely. Are the contacts on the wheel pickups clean? Make sure the blanking plate is plugged in the correct orientation. If I was trying to fault find, the first thing I'd do very very carefully is put the loco on a work bench and supply power directly to the motor using micro croc leads to see if the motor was running ok. Then I'd work back from there and check for any loose connections between motor, the PCB and the PCB and the wheel pickups. The MM071 chassis are very fussy to disassemble and one thing out of place and they won't run. Those blanking plates are almost indestructible. Are you able to run another DC loco on the same section of track work with the same 12v DC controller? Quote Link to comment Share on other sites More sharing options...
0 IANG Posted March 2, 2020 Author Share Posted March 2, 2020 I gave it to a guy in a electrical shop and he did try meter on pick ups nd motor and now I'm not sure what's up waiting for him to get back to me. Kinda regret giving it now but didnt know what to do was considering giving it to Mark's models but changed my mind after I emailed them looking to buy products they had in thier shop and online and they never responded after I requested a invoice so decided not to.

0 Georgeconna Posted March 3, 2020 Share Posted March 3, 2020 Jesus, I've seen some of these so called electricians wiring layouts and managing to short the whole thing, I have to re do it for the chap, the leccy still charged him too... dunno if I would of done that myself. Since Jim is gone to the Model Railway Club in the sky not too sure who looks after these now? I take it you are overseas? 1 Quote Link to comment Share on other sites More sharing options...
0 IANG Posted March 3, 2020 Author Share Posted March 3, 2020 No I'm in Ireland.. Ferbane Co.Offaly I'd say I'm only one in entire county west side if it anyway that's interested in model railway. I know there is dave linfield think that's his name in endenderry that's only person I can see that's anywhere near me. The guy repairs phones and electronics so a mate mine recommended him so I'm holding him half responsible to try sort the mess. Quote Link to comment Share on other sites More sharing options...

Seemingly this is why loco isn't running on dc it was as you can see from the messages above and then whatever I did it just stopped no power nothing and am completely lost to what is wrong I give it to this guy who is running am electrical shop in athlone called I be fix it he is the one who told me this is what's wrong fisrt he sent me photo of blanking chip then I got my mate to talk to him (because he recommended him) I couldn't get answer of him and he told him this is what is wrong and sent the above photo and now wants €10 for nothing Edited March 6, 2020 by IANG Quote Link to comment Share on other sites More sharing options...
