Good job. The Varistor (MOV) was protecting the circuit from the overvoltage spikes from your grid, untill it had enough and failed short and burned. That is how they roll.
I work at a battery recyclers. I estimate that 90 to 95% of all lithium tool battery packs which we receive have perfectly good lithium cells. It is the BMS that always seems to develop a fault, and it happens clear across the board from Dyson batteries to Dewalt to Ryobi. The brand we seldom find is Metabo. Metabo probably uses better components in its BMS.
I like your video very much. But I have to point out heat conducting silicon paste should be applied on the rectifier module. While I am sure the HONGFA7098 thing is only silicon rubber which can fix but not conduct heat. Anyway for such a small power it should not be a big problem.
here I added two more mosfets to a blue 10 ah pwm solar controller connected to a 150 w solar panel to charge a bank of 04 60 ah automotive batteries, the controller used to heat up a lot, now it's a little cold.
Basically nothing is happened, nothing is changed, nothing is fixed. The rectifier and the varistor is the same, only the trace between them was weak. It was not even open, because the charger turned on, but was weak to charge the battery pack.
Hi Dahen. I got a makita hammer drill and it was seriously sparking from the brushes. I checked the electrical connections and there was no problem. I changed the brushes and brush holders still sparking. I ordered and mounted a new armature and it's still sparking. Do you got any idea ? What can be the problem ? (i checked the stator also it gives exact same value on both sides when i measured with multimeter on lowest resistance. )
Where r u sir,I'm waiting your video armeture winding.if you upload 12 mm wood router armeture winding video I will wait for the video and how can I am contuct with you
I gave a 6 port charger and input section blown. I can't recognize some resistor and zener values because of burnt components. Any idea where to get schematic or anybody have one that can help me with values?

Since you classify this as a "simple repair", I'd like to see something from your hard category! Well done sir!
Excelente trabajo de recuperación y reparación. Como un auténtico relojero!
Gracias por compartir tu experiencia y tus conocimientos!
Gracias señor

Sehr gute Arbeit! Wieder etwas vor dem Müll gerettet! 👍👍!
Danke mein Herr
🔧 *Great repair work. I have a Kobalt charger I am having issues with ill be applying these repair procedures to. Thank You* Dexterous X

I was thinking the same thing regarding the silicone... I would have used thermal paste.
Good morning my friend what happened why no new videos ? Are you ok ? . We miss your videos
Хорошая работа...!! Разряжать конденсатор лучше лампочкой-меньше риска...
بژیت دەست خۆش کارەکانت جێگای دەست خۆشیە
Nice work👍👍👍🙂🤝

Oh ! You are my idol. you do so well ! watching your videos I have a lot of inspiration to create my videos. Please allow me to call you professor!
What did you fill the whole with at 7 Minutes? Just curious. Thanks for the video.

what is this capacitor 6115M? i can't find it in google.

Отличная работа. Перед вскрытием, показывай, что отключил неисправный аппарат от высокого напряжения.
Спасибо, сэр
Great work my brother
Thank you my teacher
@@zana3587 your welcome my dear brother.
what was broken on the board? 😳😳❓❓
And Thank you for your answer.
just a cut between the bridge diode and NTC
@@zana3587 Oh, I thought it was a MOV.
Thank for sharing master
A little concerned about why that lead burnt like that. Looks like a fire hazard.
Smart charge to repair Ryobi charger
Nice repair...BUT never short condensators , u can demage them :)
Hello. what happened here friend? I didn't see any damaged components, what happened?
the pcb lines between capacitor and the mosfet are broken cause a spark and pcb melt
I gave a 6 port charger and input section blown. I can't recognize some resistor and zener values because of burnt components. Any idea where to get schematic or anybody have one that can help me with values?
Are you OK??? No videos in 5 months.
Давно видео не публикуете, надеюсь у Вас все в порядке?
We want only parkside!!! 🤣🤣
hhhhh ok, i try
@@zana3587 a bit of Ryobi, WORX, Milwaukee won’t hurt 😂😂
Thanks No BGM!
Cure silicone rubber!!!??? The charger will not last long!
its epoxy
@@zana3587 why did you use that and not thermal paste?
Dahen is master👌
thank you sir
My friend...where are you?!?
i was sick
it's ryobi but the pcb build quality is no better than an ordinary chinese charger...
no idea about the quality
Like
Thank you sir
First check the fuse
thanks for the advise
잘 보았습니다
감사합니다
