I would have binned the board and used one of these DCC NEM662 NEXT18 FEMALE socket to 14 wire adaptor. At £4 with generous solder pads it’s I think a no brainer and shoved in a stay alive for good measure.
Brilliant video. What a good learning experience. I think it’s good for us all to remember the tips and tricks. I think I would like to see the 142 next. Have fun. 🎉
Hi Rich! nice fix with the class 122 those diode packages a very prone to go in Dapol locos, I believe the diodes control the lighting. when I saw the state of the board, like you I suspect either a short on the wiring but more than likely the chip over heating, and shrinking back the protection on the wires which in turn caused the short. Really enjoyed watching you taking this loco apart, It's was nice to see without me having to do it and breaking something LOL! In regards to the next loco, at the time of writing it is currently 4 on the 90 and 3 on the 142 so I'm opting for the 142 LOL! I do have both locos that I need to take apart, but I think the 142 will be more challenging LOL! All the best Tony.
Due to popularity i need to do all of them with time but yes the 142 is getting some traction! I have changed a fair few of those chips myself to date, i was tempted just to remove the PCB all together however i couldn't make up my mind on DC or DCC lol 😂
Hi Rich! I'm pretty sure I'll never attain the skill level to do anything like this, but I really enjoyed watching you bring this little bubble car back to life! Don't mind which one you fix next but know I'll enjoy watching how you fix it! All the best, Ian.
Thank you Ian, lovely words, im glad you like the video, i do have plenty of locos that need fixing so i will have many more videos to come👍, Take care Rich
Just purchased the new Dapol 121 DMU model, this is for the new next 18 decoder, think I will check all those wires for bad soldering, yours looked a mess tbh, all twisted up and thinking these bare wires shorted.??.. Great repair you did, and soldering that lighting chip was a real challenge.. well done..
@@paulkandi Thanks for watching 👍, i should think quality has improved with the advent of NXT18, also though the wiring mess may very well of been from the previous owner of the loco as it had been taken apart before i got my hands on it, its very easy to cause a short in these tiny locos so be careful 👍
Yes, can well understand, I fit aftermarket DCC sound decoders into 00 gauge diesel & steam locos, some hard wired , a lot easier than N, all my N gauge are DCC fitted, but no sound as yet, just way to expensive..carry on the good work👍👍
Thank you, im glad to hear the video makes a bit of sense 👍 hopefully some peops will feel encouraged enough by the video to have a go themselves. Take care Rich
Wow ! Nicely done TWW. That's a nice model and having just checked my old spotting book from 1980 - I did see the real 55005 in action. Back then it would have been numbered SC55005 so as not to get confused with the Deltic loco numbering. Kind regards - Mike.
Class 90 please. And what a great video. I thought that board was toast when you showed it! Do you have a background in electronics? Keep up the excellent work. 👍
Thanks Mike, i have no real background in electronics, its mostly self teaching via the internet. I should mention i did a bit of college so thats probably helped a bit too 👍 Thanks for watching. Take Care Rich
Another great video. Whilst watching and commenting another of your videos earlier (thanks for your reply!) I was actually running my 122 after some time, following wheel and pickup clean, as well as a light oil, after which it ran beautifully. I am currently running a Dapol 27, which although running very smoothly and recently cleaned, is making an intermittent screeching sound with a very light 'electrical' smell. Any thoughts?!
the worst feature of the Dapol N 122/121 is the solid wall behind the cab at the non-van end. sacreligious! I'm in the process of modelling this same unit, in mid-70s guise, when it was wandering around Scotland with a somewhat crude plate welded over the route number aperture under the centre windows. This video is very helpful to me in knowing what the 122 _should_ look like as mine is made from assorted spares got a bit of an issue with the chassis bowing - the buffer beams sag below the cabs noticeably

After my last adventure into the miniature world, watching your video inspires me to my next one :)
Class 142
I love watching these, really relaxing and interesting!! Pannier next please Rich😊
Thank you, your vote is in.... 😁
Rich. Another great video. Thanks so much for sharing your knowledge. Pete
Thanks Pete, hopefully some of it will help out others 👍, Rich
Excellent video. Very informative and enjoyable to watch.
Thank you for watching 👍
Great video very informative not sure I could do that sort of thing but love watching videos like this very helpful thank you for sharing 👍
Thank you for watching, im always pulling something apart! Cheers Rich
Brilliant video. What a good learning experience. I think it’s good for us all to remember the tips and tricks. I think I would like to see the 142 next. Have fun. 🎉
Thanks Paul im glad i could share the pain with everyone🤣🤣 cheers 👍

Brilliant once again, most enjoyable.
Thanks Chris, i cant film them all but im trying too🤣 so theres loads more videos to come, Take care Rich
Top clip top guy really enjoyed watching you fix this unit. Pannier please
Thank you👍 your vote has been added 👍
Hi Richard very fiddly, but you must be pleased it’s now working. Please look at the 90 next. Cheers Roger
Yes Roger i do like it when i fix them and i get a good result, its very rewarding. Got your vote👍

well done good work soldering on the pcb

@@paulkandi Thank you! Maybe you could fit a HM7000-8TXS in a DMU? 😁
Hi Rich 142 please, I like the methodical way you do these videos, although the fine soldering isn't easy. Thanks
The soldering is a bit tricky, just lots of practice helps i find. Im still not fantastic with the thing 👍
Great video, very easy to follow along 👍

Thanks Mike, i can see how people could get confused with the numbering, i wonder if the "SC" meant "Single Car"?
Cheers Rich
@@ThisWayWorksTWW It was because it was based in the Scottish Region.
Pannier
Just because I think you really want to fix the 90! 🤣
🤣🤣
Class 90 would be good
Class 90 please.

Screeching noise could be dry motor bearings, a tiny tiny touch of oil on the motor shaft would help here 👍
@@ThisWayWorksTWW I shall have a go at that. Thanks very much.
@@flymajj good luck 😁
class 142 next please!

very interesting would it be possible to do a dapol 66 repair
I have a few to fix so i will show them in a future video 👍, Cheers Rich
Look your film class 90 thanks.
