Re: Select-able wall wart power supply - dead

So for anyone rise in the future reading this thread, is there a faster way that I could have found this out sooner? I don't mind, I was taking it apart for fun. but for a problem like this, What is the process of diagnosing the failed parts on one of these?

Check the primary winding for open circuits, and if it has primary fuse, check that too.

Better off getting new PS, and unplug it when not in used.

Yes, and also overloading can cause it to burn out. Also, poorly designed transformers might burn out earlier too.
