You need a good quality resistance tester and a bit of experience... If you want to find problems whilst ther power is applied you use freezer spray to locate problematic components.. Most of the times a short is easy to find...

On the other website forum he is asking how to "repair" a pcb that is burned into charcoal.
When is a component or something a dead short? and how do you find a dead short when there is no voltage drop or heat? no voltage drop is like an OPEN or BREAK , cut trace
Cause an OPEN = Zero volts
Dead short = Zero volts
So what's the difference?
I´d say OPEN = ANY volts -- Zero AmpsCause an OPEN = Zero volts -- Zero Amps
Dead short = Zero volts -------- 5 Amps
Hmmm I had to think that through for a second, yes I guess it depends wich side of the open you areI´d say OPEN = ANY volts -- Zero Amps

OPEN is a floating connection to nothing. Its voltage is anything until the resistance of your meter or 'scope probe grounds it.

...How can you have zero volts and 5 amps , that doesn't make sense ...
.If you have a meter that will measure to millivolts, you can sometimes trace a short by measuring the voltage drop in the supply or ground rails. There will only be a voltage drop along tracks that have current flowing in them

big difference in pressure between the two tanks
You have an IC with a partial short of 1 ohm. Then the 5V supply has a load of 1 ohm + 1 ohm= 2 ohms.
The voltage is divided so the IC dissipates 2.5V x 2.5A= 6.25W
