[sdiy] How do you find the cause of a short ?

[Dan Snazelle]

I have a couple boards which are beeping on the continuity test between the positive rail and ground.


I cant find any bridged traces with a magnifying glass. Maybe a bypass cap blew? Or maybe......

But i have no idea how to figure out what might be the culprit.

I disconnected the power supply and the problem persists.


Thanks for any advice!!
