Konica MT-7: Shutter won't click
Hey, total noob here! I got this camera for one or two bucks second-hand. The batteries were stuck (they were "best before jan-99") and badly corroded, but I managed to get them out yesterday and remove the corrosion with vinegar. Unfortunately the acid ate away some of the metal on the cover (2nd picture) and the battery cover won't lock tight, so I put these white straps on it. Yesterday when I put in batteries and some aluminium foil, it worked and I was really happy.
But today I tried to load some film and the shutter is completely stuck. I tried opening the camera, checking if the mechanisms in the film compartment move (which they do), new batteries, more foil, but nothing worked. Sometimes it makes weird rattling noises, but that's about it. Also, when I took out the batteries, they were very warm, which doesn't seem like a good sign.
Is there any chance to repair it, or is it too risky as it heats up the batteries? Thanks!
