My Zeiss Ikon Series I Contarex has a few problems I am working through. One issue is an inoperative meter. I noticed that when measuring the two leads off the cell, it shows a sensitivity to light; but I can't find any information on what the acceptable range would be. I did find info on a west coast repair site indicating the wiring needs to be replaced but other than that, not much info. Anyone here have experience with these cameras they would want to share?
