The most obvious cause of a stuck meter is a disengaged auto-ring. Look into the mirror box, you should see a black ring held by 2 chrome pivots. If the ring is not attached to 1 or both of these pivots you will have to gently coax them to slide into the 'forks'. It is possible the galvanometer in the meter assembly is defective, or one of the thin wires connected to the spring needs resoldering. If the previous "repairer" has taken out the coil and replaced it he may have tightened the suspension screw too tightly and the coil is stuck. Easy to spot if there are tooling marks near the varnish seal to that screw. Another explanation is the needle locking mechanism is jammed and is partly engaged with the meter needle. You should be able to spot this problem when the prism is off, but before removing the prism you will need to place a small screw in the vacant screw hole to hold the spring-loaded viewfinder display of shutter speeds in place. If you don't, it's not a big deal unless you like spending a Saturday afternoon getting the display realigned! |
