Dead Dewalt 4 Port Fast Charger | Can I FIX It?

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.

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😅

[@BuyitFixit]

Nice 👍

[@mrjsv4935]

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.

[@BuyitFixit]

Thanks MrJSV 👍

[@MegaPyro83]

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 👍

[@BuyitFixit]

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.

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.

[@BuyitFixit]

Thanks 👍😂😂😂😂😂😂😂😂😂

[@mxslick50]

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.)

[@BuyitFixit]

Interesting 👍Thanks for sharing.

[@mikebruestle218]

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.

[@bienhelado204]

[@BuyitFixit]

[@terrym1065]

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.

[@BuyitFixit]

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 🤷‍♂️

[@Raven-fu1zz]

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

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

[@BuyitFixit]

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.

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.

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? 🤔.

[@Enjoymentboy]

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. 😂

@@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.

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.

[@BuyitFixit]

I would have thought the same, but someone else in the comments said the cost would be negligible 🤷‍♂️

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

[@BuyitFixit]

Interesting 👍

[@TABRO284]

I am really surprised the two boards are a mirror of each other rather than two the same.

[@BuyitFixit]

Yes, I was too 👍

[@SanchoPanza-wg5xf]

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. 🤗

[@BuyitFixit]

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.

[@peacebeuntoyou8934]

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.

[@BuyitFixit]

😂😂😂hopefully you didn't pull on it too hard 🙂

[@peacebeuntoyou8934]

@@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. 😀

[@MattBrownbill]

It surprises me to see something that won't run at 240v nowadays.

[@BuyitFixit]

Yes, a lot of things now are universal voltage 110-265.

[@smbrob]

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.🤣

[@BuyitFixit]

😂😂😂😂👍

[@pwapwap]

I have taken a cord back apart because of that mistake and then forgotten a second time. Sometimes brain is not switched on properly.

[@BuyitFixit]

Hmmm now that is something I don't think I've done 👍...yet 😂😂😂

[@renevile]

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.

[@BuyitFixit]

😂😂yes and it's still easily done 👍

[@alunjones4427]

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.

[@BuyitFixit]

😂😂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 😂😂😂😂

[@cameronchicken8439]

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?

[@BuyitFixit]

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.

[@fullraph]

I feel like it would have been really easy for DeWalt to make this thing dual voltages.

[@BuyitFixit]

Yes agree 👍

[@powertoolsrepair]

Yes, you can fix it

[@BuyitFixit]

😂😂👍

[@repairs524]

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

[@BuyitFixit]

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.

[@repairs524]

Thank you so much for your reply

[@darrenglynn597]

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.

[@visimirmedjunogovic188]

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

[@BuyitFixit]

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.

[@bborkzilla]

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.

[@BuyitFixit]

Yes me too 👍

[@pete3897]

Plugs, and heatskrink too eh ;)

[@BuyitFixit]

😂Yes, me too 👍

[@Teslamaniac]

It is also an isolation transformer so you are not getting a shock from the ring main

[@BuyitFixit]

Yes, but centre tapped to earth, so each wire on the output is around 55V referenced to ground.

[@bigfilsing]

never done that.............this year

[@greendragonmakerspace]

yup...

[@BuyitFixit]

[@ljonesj]

i cant believe how many times ive done that on a power cord

[@BuyitFixit]

😂😂😂👍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 😂👍

[@markturner7459]

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

[@dannym670]

I have a dual DeWalt charger, everything powers up and both lights flash when two batteries are inserted but only one side of the charger will charge the other side will just keep flashing but not charge, have you repaired any of these?
