    I have a nikon FM with the MD-11 motor drive with new batteries. If I
    point the camera to the floor, the md works. If I point it at anyother
    angle, it doesn't. Any one got any ideas??

    TIA

    Sounds like either there's a loose contact or the batteries are to small. I have
    a non-Nikon battery pack for my F80 and with some batteries I have to be very
    carefull when inserting them because they are slightly smaller than the battery
    pack would like. Because of this thye don't make perfect contact.

  3. If this is the case, you might try blocking them forward with a small brass
    washer, or something similar.......

    Check the 4 contacts inside the motor drive. The MD-11 internal contacts
    came to a point, similar to the head of a nail, and the smallest bit a
    corrosion caused a problem. Clead all contacts with a pen eraser and see if
    this cures the problem. Nikon upgraded the internal contact plate on later
    MD-11's with a more rounded surface.

    Also, the motor drive switch in the camera, part of the camera battery ass'y
    maybe cracked, OR, the shutter and/or shutter brake ass'y may be sticking or
    worn.
