Re: Finding fault capacitors with high current PSUs used to be the norm
A quick application of a car battery to the 12v line would sort the men from the boys capacitor wise and reduce fault finding time no end
We'd do the same thing, except we used a 5V supply with the current limit turned off, so as not to overvoltage the chips.
Regarding "Alvin" in the original article:
He even managed to get the disk working again, by buying an identical drive and marrying its logic board to the platters from the dead machine.
He should get passing marks, simply for thinking of (and successfully doing) this!
