There is also an inexpensive instrument ( about $180US ) called "Leak Seeker" from Electronic Design Specialists ( www.eds-inc.com ) that does a very respectable job of finding the location of internal board shorts. It takes a little practice to get the most out of it, but it does work.
Polar Instruments ( www.polarinstruments.com ) also makes a similar instrument called "ToneOhm", but it is on the 'pricey' side.
