I am using a 1.4 volt zinc/air battery and modified the battery compartment to accommodate the smaller cell (I'm confident it maintains constant contacts). The actual light meter appears to be properly calibrated and functions correctly in relation to the aperture and shutter speed dials, however, if I just lightly tap the camera the circuit seems to break and the meter flickers off and on. Most obviously, it seems like there just might be a wire loose, but assuming that the camera body has never been disassembled before, I don't see this as a probable point for failure when examining the mechanical complexity of the entire metering system. Taking a glance at the schematics in the technical repair manual for this machine has convinced me that I don't want to disassemble anything that isn't absolutely necessary. Suspecting that things that come off the same assembly line often meet similar fates, I'm curious if anyone on this forum has run into a comparable issue with an OM-1. I would be grateful for any thoughts/advice before I attempt brain surgery. I have a second OM-1 md body to cannibalize for parts. Thanks!
