I found the article. It uses 150 source resistor for 10 mA and their microvolt meter. A DMM on 20 mV scale should just do it but you might need 100 mA to get enough voltage drop.
Anyway, worth a try.

There was an HP note about finding shorted caps on a rail. Basically,
they used a 1 1/2 volt battery with series resistor to provide a
constant current (I think about 15 ohms for 100 mA sounds in the ball
park) to the shorted line. Then measure the voltage drop across the
circuit tracks, there is just enough resistance to get a small voltage
and track to the shorted component. I think I saved the article but
would have to hunt for it. Perhaps someone else might have it to hand?
