Awesome! Thanks! Question: how did you test the switching signal? You used a meter in what mode? Thank you!
Frequency
@@bobsoft Is it Hz%? I have the same/similar meter he's using but he switched meters. I'll try to review the video once my Internet connection is restored. Can't see enough on my phone lol. Thanks!
@@jaym5938 Yes frequency is measured in Hz
best regards
i used Uni-T 202A+ for frequency measurement, it have separate frequency and duty cycle function button, and its frequency reading is awesome
i measured the reboot frequency around 20KHz,
@Jay M it is around 20Khz frequency
Hvala vam Haseeb na razumljivim objašnjenjima, zahvaljujuči kojima i mi, koji nismo stručni ali volimo elektroniku, možemo da shvatimo suštinu problema. Pohvale za vaš trud,
i znanje koje nesebično delite !
srdačan pozdrav i posebna hvala na vašem vrijednom komentaru. Budi blagoslovljen
Very good video and easy to understand right to the point. you would make a great teacher and your multimeter is awesome. but I must say the most impressive part of the video was in the beginning when you opened the retaining clips with your fist somehow. I always fight with those to open and usually damage the case with a screwdriver doing so thank you and cheers from canada
Emeğinize sağlık efendim. Allah CC sizi her zaman hedeflerinize ulaştırır. İnşallah.
Your explanation of the topic is excellent. I have a problem. The fan is not working
Another excellent video. I think the customer would be very happy. In many countries the user would just throw the charger away and buy a new one.
Thank you thats a great video im working on my charger today was missing parts and replaced with similar got it charging outside though lol to test
It's is a blessing to have you, thank you for your knowledge
best regards

Gracias amigo por compartir tus conocimientos que dios te bendiga siempre
Hola,buen video y buenos consejos.Me podrias ayudar con un cargador de 36v de patinete que solo da 40v?Gracias
تشکر درود وهزاران لایک استاد خوب وگرانقدرم 🙏🙏🙏👌👌👌❤❤❤🌷🌷🌷
Thanks...I repaired this type power charger......aux. windind found open...thanks again sir...
wow awesome
Trouble shooting is difficult this time. I had a good look though. I want to do well too! Thanks for the video as always.
yes you are right, it is difficult to troubleshoot, but if we understand the circuit and we work logically, then it becomes like a piece of cake
wish you best of luck and success in every field of life
Mr Haseeb u are very good in explanation thanks.....
You are most welcome
Brother Haseeb the great fixer 👍
Many many thanks
Very good and useful information sir thanks for sharing this knowledge to us
Most welcome
Beautiful fix as always brother
it is my pleasure
شكرا على هاذا المجهود الكبير
Dear Haseeb, excellent video.
Many many thanks
I have a similar charger. I opened it to modify the voltage using the tl431 divider circuit. I found the tl431 but could not find the voltage divider resistors. Never encountered such a design.
thank you haseeb very interesting
You are most welcome
*thank you it's always interesting*
best regards and special thanks

Thank you master.
Nice video shot, keep it up, thank you for sharing it :)
it is my pleasure
Nice vedio thanks ❤❤
nice and easy learning given every video thank you ❣❣
Most welcome 😊
Always informative, even before watch
best regards
Can you go through a PFC LLC PSU like used in playstations
Good information 👍🙏
Excellent video
Thanks for sharing
best regards
Thank you its very good
Great!!! Thank you.
You are welcome!
hola saludos desde cuba tengo problema con el cargador esta dando la mitad del voltage que deberia ser 84 voltios en la salida me pudieras ayudar con eso
Great video, what if we dont have any voltage to the secondary side, mosfet is good it has voltage, but voltage is not pasing to the secondary side, fuse is good, bridge req is good...
Thank u so much. Informative vedeo.
Most welcome 😊
very nice video and excellent explanation sir
thanks a lot dear brother
I would recommend to use an isolation transformer when dealing with smps.
Haseeb sir..very nicely explained .. at last of video due to absence of battery u couldn't check the charger.. I have one curiosity that is it possible to create any circuit or any other arrangement with which we can check the chargers.. I am in business of e rickshaw chargers.. reply anticipated..
Very nice sir good job thanks for sharing
Most welcome
Very nice sir good job thanks
Most welcome
Very nice video sir
Thanks and welcome
Very good
Sir how BMS circuit works in this charger ? Please make video on this topic
Very good. MAŞALLAH
Sir plz plz plz one video on 16 volt.
I have not a proper knowledge about it
nice job
best regards and special thanks
Thanks brother......
thanks a lot
Loved it.
best regards
Good work
best regards
Hello my friend How long will it be outside of the charger? Is it 48 volts? 56 volts Or it starts at 48 and ends at 56 volts
Sir,Mera pass ek Ebike charger repair hone ke liye ayatha jiska primary bahut sara parts (components)burn tha ,main usme ca888 module se repair kiya hu but usme proper charge nahi ho raha hai.iska solution boliye.

Nice video Sir,
R39MF5 ic kya h 8pin nahi sir iski
Kya kaam karti h sir ye ic
it is SSD
i will explain it in detail in upcoming video, no problem
Sir, without battery how on and load testing??? Any tips available
Resistor, coil
Because electric bike many different charger available so reparing time testing problems without battery.
Please help sir
Where from we get 16 volt voltage
initially vcc voltage are obtained from startup resistor and after startup it is from bias winding or auxiliary winding or vcc winding

Va Alaykeum Selam Brother
Great knowlodge and video but I dont understand Reason my bad english
Which component was changed ? Also how is measure frequency of IC (which arround Pins )
Essalamu Alaykum
thanks a lot dear brother
i replaced gate drive resistor (connected at grate pin and ic pin number 6)
and a protection diode at gate of mosfet
for frequency measurement please check the new video 845
explanation is good sir by same method i repaired same charger it's turned on. output voltage ok but ampere decreased 3ah to 700 ma
# opto coupler good
# used various mosfets
# changed upto 3qty 3842 ic also
# TL431 also good ok
# all capositors are 100% accurately tested with capositance meter
is any differents in mosfets?
please give some suggetions...sir
please check its RCD snubber circuit
check current sense resistor (connected at source pin of the mosfet)
check output side LM358 or any operational amplifier IC for battery management
@@HaseebElectronics RCD snubber circuit is good with fr154 diode
current sence resister with 810 ohms is good
and the outpu side BM lm358 icc section is designed by chip module with small components battery charging, full off led's sections also good this is the critical problem sir i never seen yet
is any chance to fail DT transformer
Output fluctuation allso same issue same charger 17.45 v vcc also fluctuation
Me puede colaborar con el diagrama electrónico te agradezco un montón
Can that diode and resistor be replaced with normal diode and resistors..I mean other types
if we cannot find smd components, we can replace same value normal resistors
@@HaseebElectronics thanks.asalam aleikh.love from uganda
As ka load tester kese banaye manlo mujko 48v 4000w ka load tester banana ho jisse me charger reparing ke Baad load pe test karu to confirm ho jay ke charger ok ho gaya hai
👌👌👌👍
best regards
Any site provides battery charger circuit diagram
Please send me reference of the multimeter. Thank you
👍
Is CHARGAR me 358 kahi kese kam karti he ye koi nahi video banaya he. Red or green led kese on or off hoti he or BETRY conect karne se kese charging led on hoti he or charging full hone se kese cut off hoti he ye koi nahi dikhata he . Uske bare me video banaye. Bahut sari video he lekin ap jesa koi nahi samja he. 358 ki video koi bhi nahi he TH-cam pe.
Mine has a fan. It makes noise for about 3 minutes and works good. Anyone knows anything about this ussue?
battery not connect charger show green indication , but when connect battery no show start chang ?
Salam i need diagram
link where i can download the diagram please
E bike charger circuit diagram kahase download kare help me sir
I want power ic see
pls give a data sheet
When I plug my drill charger, light turns on but turns back off and it remain off. Charger doesn't work. Why does the light turns on and turns back off when I plug it in? Where could the problem be? Can this be fix?
it means its smps converter section is good.
it have problem in battery management system. so you need to check the output points and its related circuit. that it is interrupting the charging control circuit

Where from we get 16 volt voltage
initially vcc voltage are obtained from startup resistor and after startup it is from bias winding or auxiliary winding or vcc winding
16 volt not stable its fluctuating up and down
So that charger is on off /on off
How much startup resistor value
