- In this video we're going to be looking at a Dead Dewalt 4 Port Fast Charger. I was told by the owner that when he plugged it in he heard a pop followed by another pop and then it was completely dead. Let's see if we can figure out the problem and hopefully repair it!
I'm not an expert, but I do enjoy trying to fix things.

Quite impressive that the MOVs were able to protect everything else and just take the fuses out.
Yes, I was expecting more to be blown too 👍
Perhaps this why they were there in the first place. Protection against ignorance 😞
@@mikepanchaud1 Almost certainly, but IME they rarely blow fast enough :(
I don't even want to admit how many times I have done that with Shrink Wrap after soldering wires. LOL
😂😂😂👍
I swear it’s EVERY SINGLE TIME 😂
😂😂lol
Yeahp, haven't we all....!!!!🤣🤣😂😂.... and more than once...!!!
And after the unsoldering, realizing you could've just put the shrink over the smaller connector on the other end of the cable 😁.
I have left the back part off of the connector more times than I can count! 😂
Great repair!
😂😂😂Thanks 👍
One time I purchased a nice Marconi RF signal generator from a well known company on eBay. It was cheap as listed "not working". First thing I did when it arrived was check the line voltage setting. It was set to 240 volts. Set it to 110 volts and it has worked fine ever since😅
Nice 👍
Nice repair, never knew about site transformer before, sounds very good idea for electrical safety for example in construction site. Another thing to learn from this video is that it's good to check the voltage of unknown device, before plugging it in.
Thanks MrJSV 👍
First time i changed a 3 pin plug when i was 11, i forgot to put the back plate back on and plugged it straight into the socket which was live. That was my first 240v tingle through my body and 3 pinarks on the palm of my hand. I've never forgot to put the back on ever since and i always turn the sockets off. Some of us learn things the hard way but never make the same mistake again. Great troubleshooting 👍
Thanks 👍When I was around 5 or 6 years old, I remember tripping over a cable and pulling the cable out of an extension light that was plugged in. I picked up the two wires.. and I remember a burning sensation.. all of my fingers were quite blackened! and my mum had quite a shock when she saw them (although probably not as much as a shock that I had). This was when we had old cartridge type fuses and no RCDs.
@@BuyitFixit When I was 5 y/o I tried sticking a butter knife into a 120V wall socket, I clearly remember it violently shaking my hand and arm up and down before I yanked it away and went crying for Mom. It was a long long time before I got near a wall socket again.
My little brother once stuck a copper penny deep enough into a North-American 120V outlet to get the shock of his life. He was stunned, but unharmed. The outlet cover was scorched. He was around six years old.
Some years back a friend who had bought a ghetto blaster in the U.S. returned home and fitted a UK plug on it with similar results, fortunately it had only burned out the primary side of the mains transformer which was a relatively easy fix..thing is the transformer was 110 0 0 110 input so had I have known I could have adapted it before he blew it up..amazing how many people don't realise our domestic voltages & mains frequency is different
Yes, I remember years back working on a Wurlitzer juke box which had been imported. They used a 110v transformer to power it but the records played at the incorrect speed. There was a cog that needed to be replaced to change it from 60Hz to 50Hz then it all worked fine.
00:43 I spotted it. Britain runs 220V to every outlet, and this device is only rated for half that. It's a North American charger. Very weird that it has a UK-style plug.
Correct 👍I suspect it had the yellow 110V round style plug used in building sites originally fitted, and someone decided to fit a 240V 3 pin household plug instead...
Another excellent resurrection. You just know that that 13A plug has its fuse jumpered with fag packet foil. The other advantage of the site transformer is isolation, for when you are standing in that water-filled ditch, erecting lighting gantries.
Thanks 👍😂😂😂😂😂😂😂😂😂
Great fix! These chargers aren't cheap, so it's good to see one get repaired.
Forgetting to put the shroud of a plug on before making it off is annoying. Even more so with armoured cables, i should know.....
Thanks 👍yes I think I've done that on armoured cable too 😂😂😂
Nice fix sir👍 Never heard of a "site transformer" before, here in the states we don't use them so had no idea. I can see the reason for their use now, 55v compared to 240v, big difference. Having the UK plug installed was a mistake IMO, even though sold there. Great video, well done, thanks. See ya next time.
Thanks👍, yes because we are all 240v they use them for safety. I guess someone must have removed the 110v plug and fitted a 240 thinking it didn't matter 🤷♂️
Yeah normally in the US we got two phases of 120v on any power hookup so we can just select between 240v and 120v right off the line, by default it's 120v but it's fairly easy to get 240v working too
To everyone wondering why the mirror image boards: The cost to make that mirror image board is literally so small, as the most expensive part of PC boards is the artwork for the etch masks, drilling patterns and silk screen. Once that art is generated, a simple few clicks on a CAD program makes the mirror image masks. The build costs of each board are exactly the same, since the same components are used on each.
Another example I know of is a major manufacturer's audio power amplifiers. Every model of different power ratings in the product line use the exact same PCB, the only difference is the values and quantities of the components in the power supply, driver and output stages. Not only does that save big in not having multiple PC boards made, but a really ambitious and savvy tech can ADD the components (and change a few others) to upsize the power output of a given amplifier. (One of these days I'm gonna try it on a spare unit.)
Interesting 👍Thanks for sharing.
You may have to look and see if any of the amplification components are in parallel. If they are, you may need to be careful about matching all of the paralleled components from the same manufacturing batch, since the differences in impedances can make one paralleled component work harder than the other.
Whoever changed that power connector should be severely admonished!
Yes 😂😂
He should be sacked.
The people who hired him should also be sacked.
He should be “ charged”
Of course I've made that mistake with not putting the cable through the plug top first . And I never knew that about site transformers about being center tapped so potentially only 55v AC electric shock.
😂😂😂😂I must admit that I didn't either until about a year ago when I was messing with the solar inverter I was repairing and thought I'd use it as a source to make DC for the panel input for testing.
Oh been there, done that.... I once made off a 37 pin multiway connector and was 3 quarters the way through when I realised I hadn't threaded the cable through the connector shell. I am ashamed to say that I took the easy way out - made a cut in the shell so I could fit it over the cable! Fortunately
it wasn't carrying anything more than 12V and was in a location where it wouldn't be seen.... or so I kept telling myself!!
😂😂😂yes we've all done it. A couple months back I was repairing a headset for someone at the repair cafe I volunteer at. I did a very neat job of soldering the 4 enameled wires onto the 4 way 3.5mm jack... then realised that I hadn't threaded the plug cap onto the wire first .. oh well 🤷♂️
Never knew those site transformers were centre earth tapped. Great to have the explanation in the video.. Every day's a school..
Glad you enjoyed it 👍
I found this interesting because I bought one of these chargers in 2021 I never thought I would see inside one. So far it's still working great.
Nice 👍well at least you know how to get the board out now 😂😂
@@BuyitFixit true
Great fix, I was smiling when I read the 115vac on the sticker with a black plug on the end... lol. I think everyone has forgotten the plug shroud at least once a decade, lol. I could see it as you were wiring the plug and thought, oh no, lol, every day is a learning day 😂 great vid, looking forward to the next one 😊👍
Thanks mate 👍
Plugs: Those 240v rubber ones caught me out every single time. Some covers ended up with the loop cut!
😂😂😂👍
Nice fix. But I am surprised there wasn't more blown parts then you had... But now it works correct again and that's what really counts. Thumbs Up!
Thanks 👍🙂
I'll bet that epoxy in there is for preventing impact damage but it's sure to make even the simplest of board repairs a real chore.
Yes to both! 😂😂😂👍
when putting flexible wires into a screw terminal - please use crimped on ferrules! safer and keeps the wire where it needs to be.
I normally put solder on the wires but there was a bit of a discussion on another one of my videos saying that it's better to use the bare wire. I'm not saying your wrong of course, but I'm sure out of all of the plugs fitted by people (not manufacturers) in the UK probably 1% have ferrules fitted.
Is it just me? or did anyone else think for a moment Mick was wearing a Christmas Jumper? 🙂
I was 😂I recorded the first part of this around Christmas 🙂
I have NEVER (with my fingers crossed behind my back) EVER done that with a socket or coax connectors 🙂My Dad was told the electric was off to a building they were working in so he put a felling axe through the mains. Apparently his mates picked him up from the other side of the room, with LOTS of laughing of course. No wimpy 110 site electric then, they were PROPER builders.
I am currently ferreting away at doing a fresh install on a new laptop. Trying to make sure I have all the programs on it I want and none of the rubbish from the old one. Been at it for 6 Hours on and off so far, between watching you and FT8 ing. Thanks for the entertainment. Bet you would have got this all sorted by now !
Oh yes, while clearing all his stuff out from the shed I found a couple of extension cables with a plug on each end and another 2 with sockets on each end, go figure. The wires were added to my DX Commander ground radials 🙂
Nice 👍
I remember working in an amusement arcade and having a similar experience with some side cutters and an old fuse box where the lad I was working with went to turn it off and shouted "Right it's off" ... BANG.. Went my cutters, blew a hole right in the cutting part of them..
"Oh it must have been the wrong switch" no kidding I said lol😂😂😂
I don't know how much you know about bicycles, but here is something very funny. A guy I went to school with, bought himself a bike. All it needed was reassembling. He got busy. When he had finished, he couldn't ride it. He had put the pedal arms the wrong sides, the chain on the wrong side, & the back wheel in the bike the wrong way around. It took him about half hour to work out where he went wrong. Regarding putting plugs on cable, I once put the cover on the wrong way, & wondered why it wouldn't slide into place.
I didn't know that would have been possible assembly a bike but I guess so 😂😂😂👍
Eh? Chain on the wrong side? Like the left instead of the right? That doesn't make any sense. The chain guard only fits on one way. Your story is more confusing than funny. Then again, it's been a good 25 years since I rode a bike.
@@SanchoPanza-wg5xf I spent a lot of my teenage years fixing push bikes with a friend of mine. Some of the bikes had no chain guards on them. It was easy to put the pedal arms on the wrong side in this case, for that reason.
Instead of trying to figure out how many times I have wired up a plug before putting the wire through the collar it's easier to just think about how many times I actually have done it right the first time. I'd estimate three. Same goes for using heat shrink tubing. About 50% of the time I have the wires spliced and soldered before I look and notice the heat shrink is still sitting on the mat. And I go through a LOT of heat shrink...I buy it by the 100ft roll...so this happens a LOT. 😂
😂😂😂😂👍Glad I'm not the only one then. Thanks for sharing 🙂
Thanks for that feedback. We just wanted to be sure, otherwise it's a vintage Realistic PR2021 gone bang!!! Not good because these are lovely pieces of kit, we'd cry if it got ruined. It looks like the pinouts are identical. 🫡🫡🫡🫡🫡🫡🫡
Cool, yeah just a 6V regulator. Should be fine.
I have that same charger. The two outside chargers on mine stopped charging within a couple months, i took it apart and checked things out, couldn't find anything wrong and reassembled it and i was surprised but all charging ports worked and have worked for over 4 years now.
Weird, although I've had stuff happen like that myself before.
FNF = Fault Not Found. lol
I would have imagined this used a switching power supply accepting 115 or 230, how interesting!
Yes, although the Milwaukee chargers don't accept both, but you can fit or remove a jumper on the PCB on those to change the voltage 🙂
Another great fix. When replacing the brake pipes on my car i forgot to put the pipe fittings on before making the flare more than once!
Yes I think I've done that too 😂👍
IPA works great for removing the silicone
I couldn't remember if it was IPA or acetone. I did try IPA on the conformal coating 👍
Was you able to read the markings on the old components to order the replacements? Just wonder how you knew what was the correct part to ordered as quite often things can be unreadable.
Keep up the good work
Yes you could still see the markings. Unfortunately I've thrown the old ones out so I can't tell you what it was.
Yep ! I have the Tee Shirt regarding putting plugs on and I didn't know about the centre tap so ...cheers !
Thanks AndyMouse 👍
Excellent Mick. Apologies for the maybe obvious answer question...On the varistors, how did you know what part to replace them with? Did they have the markings intact or on a SMPS does it not really matter as long as you get a suitably high voltage one? Cheers
Thanks Vince, they still had the markings on them, but as long as they are the correct voltage I don't think it makes a lot of difference.
Jeez, fella. I took the time to read your disclaimer and found some errors that ought to be corrected if you expect it to hold up in court:
"... that may [BE] dangerous...."
"... injur[E] yourself...."
I am a law-abiding citizen and thus have duly Liked this video. I am already a subscriber. 😜
😂😂😂Yes, I think it was 'Mymatevince' told me too. I fixed it in subsequent videos 😉👍
I love to watch your troubleshooting.
Thanks 👍Much appreciated 🙂
Great job there, mate. Just removing all that gunk was quite an ordeal. Great work, mate.👍👍
Thanks 👍
I think if you heat that stuff up with a hot air it would soften up and be easier to remove.
Brilliant fix as expected Mick, I remember years ago hifi’s and other goods had a voltage selector on the back 115v-240, that was so dangerous. I wonder if there was a different transformer taps that you could of made it 240v? 🤔.
I have left plug covers off before, also aerial plugs I forget to put the cable grip and top ring on, which is a pain after soldering the cable in to the plug part. Often do it with heat shrink too lol. Thanks for sharing !😊
Thanks mate. There wouldn't be different taps on this as it's a switch mode PSU. I did look to see if there was a setting as the Milwaukee chargers have a jumper which is fitted or missing depending on the voltage required.
@@BuyitFixit oh fair play Mick, that makes sense being a SMPS I didn’t think that through lol 😂
@@wisher21uk No worries mate 👍🙂
just seen this video now. It would've been interesting to see if that one could've easily been converted to 230V.
Usually those companies do not completely redesign these things, at the end it's usually just a simple population option.
There was that option on the Milwaukee chargers (a jumper position marked J1), but I couldn't see anything similar on the Dewalt.
@@BuyitFixit probably would require a comparison device or a datasheet for the involved components
Always read the label. Good fix! Well done.
Thanks! 👍 🙂
First, I had NO IDEA England used that clever site transformer. Brilliant idea.
Second, You can't use a Milwaukee tool to fix a Dewalt tool. That has some bad joojoo I think.
Thanks 👍😂😂😂😂
Yeah , I spotted that real fast , I guess because I'm in 110 V country ...... Oh yeah the famous I forgot to put the coax screw housing onto the coax before soldering the body on , radio microphone plugs also , I owned a radio shop for 20 years and forgot to do that less than 50 times , it becomes 2nd nature after a lil while ......... I'm curious about that 110 V construction site transformer , are a lot of electric tools over there 110 V ???? It would seem that would be practical that USA made tools would make all tools 110 V due to motor design and such , instead of 110 V USA & 220 V for 220 V countries ..... That was a great from the get go diagnostic and another one is saved ........ Take Care Mon Ami......
Thanks mate 👍pretty much all home / diy appliances are 240V. Tools for use on building sites are usually 110V to reduce risk of electrocution as they are probably going to be used in muddy or wet environments.
UK uses 240 for Tea. Boiling a kettle with 110 is hard work.
Yes so I've heard 😂😂😂👍
I've come to the realization that those things that are a nightmare to disassemble are the easiest to fix haha
Yes, all of that silicone was a nightmare 😂😂👍
15:42 Many many many times. I have soldered and crimped expensive connectors only to find out that I forgot to put a nut, washer and seal on the cable FIRST.
Yes it's easily done 👍
Not moved past the 3:15 mark yet but, make a mirrored board make not sence from a cost perspective, make one board and fit two of them.
I would have thought the same, but someone else in the comments said the cost would be negligible 🤷♂️
yes i have done that put on with out the outside cover of the plug
👍yes I'm sure it's not the last time we'll end up forgetting either 😂
@8:31 - I have old man ears, but when you took these measurements, I actually heard the beep!
😂😂👍
great repair 5* i guess the worst part was getting to faulty components under the silicone!!!
Thanks 👍yes, getting the boards out was the worst part 😂😂oh and forgetting to put the cover on the plug 😂👍
every person has done the same thing!!@@BuyitFixit
I was using a Dewalt cordless power tool charger on a modified sine wave inverter one is day it quit working when I had time I opened it up to see why and found one of the wires that was soldered to the board had gotten hot enough to melt the solder had a auto battery maintainer and charger that did the same thing since then I've found utube and know that a modified sine wave power supply will create a lot of heat
Interesting 👍
Absolutely amazed that was economically repairable after getting double voltage 😂
Yes, I was surprised too!👍
Yeah well, again many folks don't realise that frequency & number of poles has a direct effect on AC motors.
Good man! Getting some tradies out of trouble.
Thanks 👍Yes 😂😂😂
The set up is just like an amplifier both circuit boards are identical. ( Two mono blocks ) to make (Stereo).
Yes, quite similar 👍
Me too with the 110v plugs and how many old rubber 240v plugs have you seen with a cut on the cable entry
I used to make audio cables years ago and quite often forgot the cover on 1/4" jacks or XLR connectors 😂😂
Thank you for this video. Much appreciated
Thanks 👍
@@BuyitFixit could you tell me what fuse to buy
The replacements I got were from Ebay. TE5 392 8A
Very interesting video. Subscribed.
Thank you 👍I've fixed quite a variety of interesting items. Hopefully you'll like some of my other work 🙂
Well done on that trouble shooting & repairs. I'd be pretty sore at the fella who sold me that knowing he changed that plug to a 240V. Good Lord must have been watching been watching over him that day because that could have been much worse.
Thanks 👍I had been expecting it to be much worse such as exploded caps, bridge rectifier and mosfets, so I was surprised too 👍
I bet I have forgotten to put the shroud on at least 20 times , I’m being conservative with that estimate 😂. Great fix
Thanks 👍yes me too 😂😂
Cannot count the number of times I've forgotten to put the thing on the cable (whether that's part of a plug or heatshrink or something else) before working on the cable.
I glad it's not just me then 👍
15:37 One time, I forgot to screw back in the big bolt that held my car's steering wheel on. I can laugh about it now.
😂😂😂hopefully you didn't pull on it too hard 🙂
@@BuyitFixit
Whilst in the fast lane on a dual carriageway, I leant back in my seat and the steering wheel came off in my hands. I managed to engage the grooves just enough to take back control before the road curved. Like I said, I can laugh about it now. 😀
When you were removing and resoldering those components it was extremely hard to discern the details. Stabilize the piece, zoom in a bit, and don't fast-forward through the melty parts. 🤗
Sorry about that. I'm not sure what people find boring melty parts or people screwing in screws for instance. So I normally speed through those bits.
Cheers Canny Lad and Many Thanks.
Warmest regards
Wayne & Nina
❤️❤️❤️❤️👍👍👍👍👍👍👍👍😊😊😊😊😊😊😊😊
No worries
Yep same with heat shrink.
😂😂yes I've done that before too!
Nice fix Mick, Boom Boom 😁
😂😂😂😂Thanks 👍
I love the weirdness of UK site transformers.
😂😂😂😂
I am really surprised the two boards are a mirror of each other rather than two the same.
Yes, I was too 👍
Very nice fix, the owner was lucky there wasn't more damage. But will it now be of any use to him, you might end up with this yourself. Thanks for sharing.
Thanks 👍He'll just have to get a site transformer to use it.
Connect this two power suplys "in line", then You can plug into 240V line:)
Someone else mentioned that. I'm not too sure how well two switchmode PSUs in series would work.
Thanks for making my Saturday!
My pleasure, and thank you for making mine with your kind comment 😊👍
It's my weekly therapy
I have taken a cord back apart because of that mistake and then forgotten a second time.
Sometimes brain is not switched on properly.
Hmmm now that is something I don't think I've done 👍...yet 😂😂😂
Ha Ha yes many times I done the same. The worst one was a 21 pin connection plug way back in the 80s. Pain in the arise having to unsolder every pin just to start again, Me gov was not to pleased.
😂😂yes it's easily done. I've done it many a time. I think the last one before this was on a headset replacing a 4 pole 3.5mm jack, and it was enameled wire. I did a really neat job soldering it all up, end then realised 😂😂😂😂
Hi, a good fix there and thanks for explaining the site transformer.
It's odd why they went to the trouble of designing a 'mirror image' board, when they could have used 2 identical boards ?
Weight distribution might be the reason.
Thanks👍yes I thought the same too.
Possibly, but then what if it were just single charger? I would think a company would put profits first rather than if their charger was balanced 🤷♂️
@@BuyitFixit Remember, these things are supposed to be bought by serious campaigners, 'bespoke engineering' needs to be done to and accordingly charged for.
Brilliant!!
Cheers 👍
it's about 10% of the time that i forget to put the top on the wire first, you would have thought that i would have learned by now, i have only been a electrician for 15 years at this point.
😂😂yes and it's still easily done 👍
I bet the original owners stuck that plug on because they used a 4way extension with a 110 plug on it cheaper than buying a 110 4way seen it loads on building sites 😂
I've not worked on a building site before but I could well imagine it 😂😂😂👍
Then the twit [autoplioted] and plugged it into a normal socket and 💥🤨
Dad, i need some support. Mom told me it was a wild night in december of 1983 in glascow.
😂😂😂😂😂👍
I can say honestly that I have never done that--------------- on camera!
😂
😂😂😂😂👍
Darn blasted "silikin!" Nice to see you get a repair that doesn't involve several puzzling pauses, educated guesses, and ordering chip programmers from China.
😂😂😂👍
It surprises me to see something that won't run at 240v nowadays.
Yes, a lot of things now are universal voltage 110-265.
USA is standard voltage of (115 volt supply) Europe is 115 to 230 volt and Japan has (100 volt ) AC supply. Building sites max is (110 volt / 16 Amp) yellow cable.
Guys this is one of the most beautiful and interesting channel on youtube. Have you a Patreon or something else?
Thanks 👍I've not looked into anything like that as of yet.
I feel like it would have been really easy for DeWalt to make this thing dual voltages.
Yes agree 👍
It is also an isolation transformer so you are not getting a shock from the ring main
Yes, but centre tapped to earth, so each wire on the output is around 55V referenced to ground.
This is a typical right to repair case, I would say. 🤔
And thanks for the tip to remove nasty things with the rework station, I might use it on my mother-in-law.🤣
😂😂😂😂👍
you have everything linked in your description except for the parts. i can’t find the part numbers. if i go to the dewalt website they have service manuals but not for this product. the rental company is having a steel building put up and they installed a box of outlets for the contractor with welding outlets without realizing that the regular outlets in the box are also 240V so it fried the contractors charger and so the rental company just paid for a new one so i just ended up with the old one but i don’t have the manual or a parts list and it’s not on their website so im wondering where you got those parts?
I can't remember the number off hand (you might be able to read it from the original varistors still). Something like a MOV-14D201 which has a maximum voltage of 130V.
Good job !!!!
Thanks!!
never done that.............this year
😂😂😂😂😂👍
I'm kind of surprised DeWalt would sell anything in Europe that wasn't functional from 100 to 250 Volts. You certainly pay a premium for them.
Yes me too 👍
Another great video! Can I ask what rework station are you using? Thanks.
Thanks 👍do you mean my iron? Or hot air station? I've just upgraded my hot air one this week as I was using the 858D clones but just got a second hand atten-872D from Ebay the other day which I haven't really used yet.
@@BuyitFixit I meant your hot air station. Thanks!
Hi
My charger got some serious illness....lots of burnt components and i have a problem finding any info on smd ic ....it is U2 on the board, and it is 532RRK.
Any help woud be appreciated
I haven't got the charger any more so I can't check. If you have any pictures of the area you can send me an email at the channel's name at out look dot com.
Can you convert this to run on 240 volt as I remember you repairing a charger before and you said just connect something and it goes back to 240 volt
I did have a quick look, but I couldn't see any placement for jumpers or anything so not as straight forward as the Milwaukee one to convert. Someone suggested wiring the two units in series, which might work, but I don't think I'd be keen on that.
Thank you so much for your reply
The worst I've seen was forgetting to put the backshell on a 32 way connector and discovered at completion of all the cores! Not me thank goodness..
Ouch! I bet that was a bit of a sickener
Nice job Mick, as always. What do you think it would have taken to convert to 220v? just out of interest.
Thanks mate 👍Not sure, I did have a look as the Milwaukee chargers have a jumper which is either fitted or not depending on the voltage. Someone in the comments suggested wiring both chargers in series but I didn't fancy that.
@@BuyitFixit, I'm not sure I would fancy that either, but I don't know enough to know if it work or not. My knowledge is no where near yours, ok, so I'm approaching this probably more simplistically than I should. But My first thought was that either all of the components in there are only rated for 110v which would potentially be a real ball ache to swap out OR they're already geared up for 220v and the jumper you mentioned simply puts some other level of voltage regulation in front of the 110v circuit so it only ever see's 110v, if that makes sense.
Yes on the Milwaukee charger it's pretty much what the jumper does.
Plugs, and heatskrink too eh ;)
😂Yes, me too 👍
i cant believe how many times ive done that on a power cord
😂😂😂👍I've done it on all kinds of plugs. I was fixing some headphones a couple months back and forgot to put the 3.5mm jack plug top on the cable first. I made a really neat job of soldering all the wires too before I realised 😂👍
My normal cock up is to solder the cables before putting them through the heat shrink 🙄
Yes I've done that plenty too 😂😂👍
Exceptional work my friend 😊 One question, From watching Big Clive and the other United Kingdom Geniuses 🦁I thought all UK plugs had a fuse in the plug itself? Should that have not saved this charger? 🤔 or was this plug a chinesium no fuse plug 😅 Love your videos 😇
Thanks 👍Yes all real UK plugs have fuses. This one had a 13A fitted, and the fuse in each charger board was 8A. Because both boards didn't fail at the same time the 8A fuse blew first. Hope that helps 👍
Replace the capacitors and the varistors to 300 v ones, then you can use it at 220v
That may work, I'm not sure if anything else would need changed or how safe it would be. The Milwaukee chargers have a link on the PCB so it's just a matter of soldering a link or removing it to change the voltage.
retired spark now,if i had a fiver for every time i did that i could have retired at 55 🤣
