Check the terminals at the breakers they get a bit loose and make a bad connection, loosen the nuts and even sand the eyelets. They can throw you a curve with the test light test, you hit the end of the stud and have power, but it don't transfer to the eyelet.The 30's don't have a circuit board.

That is more like a printed circuit, I have seen the plugs go bad on them from shaking around.
