Today I went to a local flea market and purchased a Focal XL-303 camera. I was very excited to get home to put new batteries in it and watch it work. Yet when I opened the battery compartment, I saw that everything was corroded. I cleaned off the conducting heads with alchohol and got everything in the best shape I could, though there is still "blue" on the heads a bit. I put new batteries in and pulled the trigger of the camera. nothing happened. I tinkered with some of the buttons. still , nothing happened. Is it supposed to turn even if there is no film in the camera? is it supposed to buzz or something? am I a complete moron? Probably. Any help or Idea of whats wrong would be greatly appreciated. :]
