Kevin, I agree with you and your 1st inspector. Test is by far no guarantee that wrong components will be found. Even a full blown operational test at temperature extremes will not weed-out "all" wrong components. I remember an experiment I did about 20 years ago where I tested a group of PWAs before they were inspected. Of the ones that passed test, about 20% of them had wrong or reversed components that I later found.
