120v AC, full wave rectified, produces 120 x root 2 DC volts which is 120 x 1.414 = 169.68 volts! In Europe at 220v AC the DC rectified voltage will be 220 x 1.414 = 311.6 volts and in the UK (240v!!) that becomes 339.4 volts! You have been warned, especially when that voltage MAY sit on those 400 volt capacitors for many hours, sometimes days!!
Found this video when I was trying to find out how many cores are in the cable before I cut it as I want to extend it, as the wall holder for the cleaner I want to put quite a distance from the charger. Thanks to the video I now know - thanks. I am aware of volatage drop across distance but I just want to extend the cable by 1 or 2 metres.

love fixing things myself, and while getting ready to say you should get a finer tip soldering iron and then you said it. I have a DC31 and it has 3 wires, was hoping a video would show me a pinout :(
One little question , what is the diameter of female charging socket on the battery , 7mm or 6mm? I just meausred almost 6 or 7 mm? İ just one buy a spare one, that is why i m asking Thanks in advance
Same issue here.. those wires at the connector are just rubbish and break easily. I have had to buy two in two years and now I have to buy another. I am gonna see if anyone can fix the chargers!
Meh, it's only 120vac there right? Fairly safe. 😉 It's 230vac here, slightly more to zap yourself with. I hate throwing out something that can be made to work too, but I'm just really cheap. If you're soldering to circuit boards try tinning (thin amount of solder) the wires before passing them through the board holes. This means you need less heat near the board and the solder will flow from the wire onto the board, the tracks have a habit of lifting if they get too hot. Used to work for Motorola back in the day doing surface mount test jigs. That's eye wateringly finicky work. Btw those dinky little capacitors are fairly safe but larger capacitors can charge to thousands of volts and several amps regardless of the supply voltage. Check an old fashioned camera flash out, some of them charge to a couple of hundred volts from a 3Vdc supply, and if you have an old tube type tv lying around....... don't mess with those caps. They can be lethal.
+Alex Arcano Yeah it's 120 and not that bad. I just have this thing for hating the feeling of electricity. Our electric fence is about 5000V but zero amps so harmless really and it still gives me the willies. I had a good shot of something when I was a kid living in Venezuela, and it was enough to cause my muscle to seize up. It's that feeling that has stuck with me and I am reminded of it every time I get near electricity. That sounds like to would be finicky work. If I don't eat properly (like yesterday) I get a bad case of the shakes and it makes that type of work difficult. All the coffee I drink probably doesn't help either. I've hear that some of the old flashes can pack a punch. I used to be a professional photographer and I remember learning about all these hacks guys were doing to their flashes, and everyone talked about some of the dangers with the old vivitars. And thanks for the tip of tinning the wires. That makes a lot of sense. I've have to do that next time I'm doing something like this. I appreciate your conversation and insight. Cheers!
+Simple Little Life no worries. yup, I remember as a kid hacking a broken old flash and using it to make rudimentary stunner, hurt like a son of a.... Aaanyway, I have had a gas soldering iron for the past couple of decades or so that you can change the tips on, damn handy thing for field repairs where there's no handy power supply, has a variable heat output for delicate right up to heavy tasks and it's just the size of a chunky pen. Worth the investment, in fact it's been my only soldering iron for years now, never let me down.
I have a charger Tronic T4X Car / Motorbike charger model: KH3157 that have no current at the output needed the electrical scheme of this circuit if I could help thanks.
Do not presume that your charger has an identical circuit or even a similar one. Switching DC supplies all work to SIMILAR principles but the exact layout and components will be VERY different and easy to screw up. If your circuit board has a number try using Google to find the schematic using that part number. Use all the part numbers you can find. Often the supply part number and for which you may well find the schematic is printed or written or typed on the top of the main transformer (usually the biggest component and wrapped in a pale yellow tape.
Ultrasonic welding wins, on cost. mean bastards. I just had a fully shorted bridge rectifier and exploded fuse thing. Just use a safety switch on your bench, for a start.
Showing bad practice is just as bad as giving wrong directions. What I am referring to is your handling of a live mains wire. Any live mains wire, no matter the voltage, has the potential to kill you because of the high amps. And showing this level of recklessness as an example for others to follow is just no good. Wether you intend for this to be a journal or a guide makes no difference. Someone is bound to follow your steps as the example and might die from it. Arguably they should do their home work better, as should you have. Otherwise a great video. I fully support diy, fixing stuff yourself and all that. Good luck to you :-)
@@DazzaDirect - totally and utterly wrong. It's the POWER that kills you. Watts = Volts x Amps. High Volts and low Amps - won't kill you. Examples: Van DeGraff generator, Plasma ball, spark plug wire, rubbing feet on carpet then zapping somebody. These are thousands or even tens of thousands of Volts! Yet 110V 30mA via your heart might kill you.
You get a thumbs-up for remembering to thread the wire through the cover before soldering.
I'm impressed you did that.. I'll have to buy another one because I couldn't do that...

Calm down. It will only give zap to fingertip if you accidentally touch both leads.

The 'goop' is Silastic. it's used to add strain relief, reinforcement and general protection.
Oh cool. Thanks for sharing that. Always a good day when you learn something!

Dude , this is amazing and you are a great master
Awesome job. diy is the best way to go. Even if its just for learning.
Thank you very much! I couldn't agree more. Cheers!
Awesome.. Thanks for the DIY video.
Thank you!
Top work....only way to avoid the throw away society we now live in.
Bought a new V6 battery still won't charge. I'm thinking the charger is bad like yours. Nice work on the circuit board. I can buy one for $32.
One little question , what is the diameter of female charging socket on the battery , 7mm or 6mm? I just meausred almost 6 or 7 mm? İ just one buy a spare one, that is why i m asking
Thanks in advance
What do you call the pluy that goes in the batter what type is it?
It is a custom plug as far as I am aware.
Is this DC44.
Same issue here.. those wires at the connector are just rubbish and break easily. I have had to buy two in two years and now I have to buy another. I am gonna see if anyone can fix the chargers!
Congrats on the successful repair.
Well done. I see you have setup a small workshop. What are you doing with your drilling machines and vice?
Awsom job!
THESE electronics are made to break. Consumption trade

Hi.can u fix my dyson charger.?! Tnx for d video
