There's another linkage to check. Take the lens off and you'll see a linkage on the right, when looking into the body's mount. The little lever should be near the top, and should freely move downwards around the mount. Its spring-loaded and should move back up quickly & smoothly (if you let it go it'll go back with a "snap"). The body uses this lever in conjunction with the electrical contacts, to know what the aperture setting is. If the lever has somehow become jammed in its lowermost position your camera will show a really small aperture regardless of the lens setting with an A-series (or later) lens mounted.
