Isn't that what I said. See what happens when you ask an engineer about something?
There are a couple of other test I could of given but these require a highly technical understanding of electrical properties. The Smoke Test comes to mind. You bypass all fuses and then load up a circuit until the smoke comes out. You then make note of the smoke location, repair the area and put the smoke back in.

NOTICE this test should only be performed by a highly trained and experienced person.
