Unfortunately the manufacturer did not equip this unit to be robust . My charger glowed orange inside and smoked on it's death stroke. After a quick examination, I made the discovery that the ST Power Mosfet exploded and separating it into two parts. The fuse did not Blow. fortunately for me it did not start a fire. Needless to say We are very, very disappointed at Bosch!
The blinking led generally means faulty battery. Sometimes you can get a faulty battery working again by charging it with a separate regulated power supply.....sometimes not. Worth a try, though.
Siempre que hacen el vídeo la reparacion es facil muy sencilla el cargador mio le cambie el transitor mosfet y tiene transformador bueno 18V pero no carga la bateria por eso digo los vieeo no son todos para las cosas difil siempre es sencillo pegar un cablesito o poner estaño y finciona guaoooo
very interesting superb video. I just fixed a faulty charger the output lead was faulty soldered a new cable and now working.
Great video.Have much some important tips for repair.Thank you
Thank you.

good video. whats the fuse value? i see normally fuse is glass type what do u call the fuse that is broken in this video ,
As long as I remember there was 2A fuse
what was on the Q-tip that you rubbed on the pcb after you soldered the fuse into place? Thanks
Isopropyl alcohol
Very helpful. Thanks
Thank you!
thanks for sharing
transistor reference please
I tried to jump a wire on the fuse, but the problem the small transformer lokking thing got sparks and burned. What seems to be the problem?
Probably shorted mosfets.
how about if the green led blinking and battery no.charching? what is the normally voltage between pins?

friend what is the value of resistor number 6?
Hard to say. I dont have it anymore
I have same charger problem is that voltage is less (8v)......what can be reason?
Same problem..u have solutions?
Faulty capacitor? Voltage regulator?
what is the fuse type? and amps size?
Basic type. 250v, 2A

I don't speak Spanish
Hello sir plz send me close pic of all pcb .bcoz I hv same board with burnt resistors near power MOSFET 3n80.. I ll be very thankful to you
Hello. Unfortunately I dont have it anymore. It wasnt mine.
This other video has some close-ups if you stop the video at the right time. ua-cam.com/video/sNPQwejRsI0/v-deo.html
It even has a cool schematic, too
