The diode should not be replaced . the original is an SB26 type schottky diode with a current rating of 2A . The FR1007 is rated at 1A and is NOT a suitable replacement. There should be no need to touch the diode since it is part of the secondary voltage circuit which would not be affected by the input voltage change given that the transformer primary winding has already been adjusted to produce the same secondary voltage. Also interesting to note is the the original varistor is rated at 270v so a 300v varistor should be fine to use.
after replacing the varistor, and remove the bridge, can i added the switch to the bridge, so it will work on 110v and 220v with a flick of the switch?
I have blown mosfet and it’s missing it’s part number.. could you share me the mosfet number from your board ?? It would be very helpful to save ma charger.
I have the same problem but, what happen to mind is ,,I plugged in to 220v current without doing anything yet to the charger .....it is still possible to change the varistor or it is already broken? Thank you
I've experienced the same issue. I've done everything it is saying in the movie, but it doesn't work. I think something is broken but don't know which part.
Hi, I'm from the Philippines and I accidentally plugged it in a 220V directly, may I know what is the initial action that I can do in order to troubleshoot the board? What part will be damaged initially?
Just finished this. Works perfectly. I couldn't find those brands of varistors but I found a different one that's 10mm 471k. Works great. Thanks!
thanks

Thank you very much!! Have replaced the diode (D2) as well for 1A 1000V.
Thanks! Excellent tutorial!
Amazing. It worked for me.
Thank for your sharing
Thank You.. i follow your demo, And it Works!!!!
Thank you very much!
Все работает!
Thank you it's works,
Excelente video. Consulta los capacitares no hace falta vambiarlos ?
Would this be the same varistor TVR10471 that went pop if I plugged it into 240v and blew something up?
after replacing the varistor, and remove the bridge, can i added the switch to the bridge, so it will work on 110v and 220v with a flick of the switch?
PWM the controller failed. Write the name please. The letters "top...eg" are read. thanks
Help, when I stretched out the circuit still connected. So, the capacitor is getting hot. The charger is die. Any suggestions to fix it? Thanks
Looks fairly straight forward. Good for 220VAC 60 Hz Philippines? Is there a max current to be worried about?

Nao tem como muda pra bivolt asim e so 220 nao fuciona no 110 eu queria nas duas voltagem
Hi I have charger model 48-59-1801 do you know how to convert this to 240v? :)
I modified my charger according to your instruction but it has hissing noise when charging. Is it normal? Will it damage my battery?
Hi, can you please give me value of NTC Thermystor ? I need to replace it ! Thanks a lot.
Estaría muy agradecido si hace una convención de cargador hilti C 4/12-50
Awesome! Do you know what is required for the european socket?
Just get varistor 14d431k. Will it work?
I love you!
Hi, it's still work fine now? Thank you
Can I use 20D471K instead?

i have same issue i plugged into 220v directly
you need to replace TOP256EN IC
Can you also charge the m12 batteries?
Yes of course...
@Geo programmer can i use TVR 14471?
I do not know ,I did not use it
Geo, thank you for your video.
I used the 14471, works good. If someone wants to know.
very good
What about convert frequency 60 to 50 too؟
Not important. Frequency hardly ever matters unless the device has a an AC motor (like a kitchen aid).
Hello, I have seen another video of this modification and he changes a signal diode as well called FR107 1A, is this necessary?
can you send me link of another video which you watch ?
Hi... Can i use 14d471k varistor?
Did you use it ? I'm in the same situation
Yes you can.
@@noyelk yes working great

Hello friend, can you upload a video transforming a Milwaukee M12 charger from 120 V to 220 V ?? I need your help 🙏🙏🙏
write a exact model!
Geo Programmer Hello, the model is 48-59-2401, I live in Chile, here we use electricity at 220 V, I appreciate your help.
I will try make a video about it in near future
Write Here your email adress And send you a scheme
Geo Programmer Hello, I leave my email vhermosilla1@gmail.com, I need a good description of what I should change. thanks for your time
Condesatoru 110v nul schimbi cu unu 450v 🙄😂😂😂😂
Sa poate si fara el atunci
You forgot to replace the diode to fr107
Work perfectly Without Diode....
@@GeoProgrammer hi, do you know what function does the diode fulfill?
@@gf975 hello, do you have an answer about this diode fr 107?
@@gf975 Yes I know
I made it Without Diode And works fine
