Hey there, I found a Minolta 7000 Maxxum that belonged to my father in the basement. I attempted to replace the 4-AAA batteries and the 1-2016 internal battery. I camera has power but the shutter does not work or move. Also, the camera does not grab the film like it is supposed to when I attempt to load any film. I know that the film must go passed the red spot and fit into the reel. Any suggestions would be helpful. I have included photos.
