I recently picked up a clean OM-2 body super cheap. It was sold 'as-is',
i.e. wouldn't work. Of course there weren't any batteries in it so I was
hopeful. I put in new batteries and it worked perfectly, but then wouldn't
work at all a few minutes later. I pulled the batteries and found that
there was a .25 Amp load on the battery! Later I found that the load varies
between 2.5 to 5 Ohms across the battery terminals when the shutter is
cocked.
I (don't listen, John H. :-)) pulled off the top and bottom covers and
poked, prodded, pulled, moved, etc., etc. (about 3 hours worth of etcs.) and
found that the short goes from around 150 Ohms when shutter is released in B
to the 2.5 - 5 Ohms when shutter is cocked. The heavy load starts when the
wind lever is just barely moved.
The area causing the short appears to be to the right of the lens (when
looking at the lens from the front). From the bottom, pushing a vertical
linkage (part of the cocking mechanism)forward will cause the short to go
away (well, to about 1 MOhm), pushing the other way it goes to full load. I
suspect that I can get to the area causing the short if I can remove the
lens mount assembly, shutter ring and all.
The question is, can I peel back the leatherette covering, remove the 4
mounting screws, and rotate the whole lens mount/shutter ring assembly up
and out (still connected) without disconnecting the shutter string and
wiring?
Any suggestions or info??
Thanks, Tom
