Good Day to All,
I have a general Elec Question.
What would cause a resistor to blow?
I have a makita battery charger, and it stopped charging. I opened it up to find one of the resistors were blow, with burnt residue on the PCB. I tried to decipher what the resistor value and think I determined it being a 0.1 ohm resistor. (It was blue in color with 4 bands or Brown, Black, Silver and Gold)
I therefore brought some 0.1 Ohm +/-5% resistors yesterday, they arrived today and so I soldered one in to position. Plugged it in and bang, it went again.
Any ideas what I should be looking for that would cause this?
Thanks
