But you really want a Milli-Ohm Meter to find shorts with more precision
when it comes to connections with several components on there, about 0.1
milli-ohm resolution. That lets you pinpoint the short directly to the
sport on the pcb, even between the next pin on a chip. I just found a
place online the other week that has one for $150 from Ruby Electronics,
other costs 3 times as much, but I still have to wait to get one
myself--other bills still have priority :)

I have a none destructive method of locating such
shorts. It requires
a bench power supply and a good DVM.
Has anyone here used an ESR meter to locate a short across the
power rails? If so, what's the technique?
