I agree completely. It's funny how often we see this sort of thing done,
though inadvertently. The argument I frequently hear is, "well, I hook up
the 5-volt supply to my welder (at 5 volts, of course) and it won't hurt
what is supposed to operate at 5 volts . . .

I would never recomend passing a high current through
a possible short to
clear it. You might well do a lot more damage, especially if the short is
not the 'weak link'...
Similarly the old electrician's 'trick' of shorting out a blown fuse and
seeing what smokes is a very bad idea. That which smokes is most probably
not the original cause of the problem, but it is now damaged and will
need to be replaced, along with the (still unknown) original defective
part.
