Looking at http://www.cameramanuals.org/voigtla...ito_cl_clr.pdf its obvious that the camera has a Prontor 500 LK shutter, http://www.butkus.org/chinon/booklet...ntor_500lk.htm . Read through the service instructions and decide if it is something you want to tackle. The meter may depend on the shutter working properly or at least the aperture working and the speed ring moving properly.

I'm not familiar with the camera or this shutter.
