An ohmmeter helps you to find out if the wiring is ok. Your problem seems a mechanical one and there are often screws and other tiny metal chips that are attracted and then caught by the magnetic parts of the moving-coil meter, so that a proper rotation of the coil is no longer possible. Another problem with those meters is that the bearings can become too tight over time for a reason I do not know. I think, however, that either the frame of the coil or the material to which the bearing pins are glued somehow expands resulting in too much tension or friction in the fulcrum shafts. Loosening the setscrews of the bearings may cure this. |
