for a 10uF capacitor, it's damned difficult to determine which lead is connected to the outer foil for capacitors of this value, and above, in theory because impedance to typical test frequencies is low, either way. I tried all the well known methods, and I never felt that I got a definitive result that distinguished one orientation from the other. I don't know where the cut-off point might be for getting a reproducible unequivocal result, but it's below 10uF for sure. That said, I did not try very very low frequencies, where Z might be high enough to make a determination, like 20Hz and down.
