Title: Konica S2 Sheared meter wires, stuck shutter.
Post by: newindustar on Feb 28, 2006, 11:48 PM
I received a very nice like new S2 with Stuck advance lever and fallen off rf mirror. Using all the great links mentioned here and via Google I jumped in. I never put a battery in. The irises from both front and back were completly closed.

 Well I am down to the meter cell rewire.  I am stuck at one point now. My meter cell wires sheared off at the level of the aperture ring. I have the whole camera apart with the shutter seperated. I need to run new sensor wires but I can?t access the tiny

On the one hand you say you want to restore the beauty, on the other you consider drilling new holes, I guess this ambiguity in your articles is why there have been no responses to your questions. My advice is, as all you need to know to restore/rep

 There is some trick to getting that aperture ring off. I think you have to unscrew a stop post on the back and then rotate the ring to where some cut-outs will pass over the tabs. (This is from memory, but it's something like that.)

 Well I certaintly don't want to drill any holes . This would not be an issue if that silver barrel ring had not been so frozen. This is also my first camera repair and I don't have the special tools so I don't see why my queries should go unanswere

I removed the same stop screw I had tried before and the one you referenced and it worked. I guess I had not found the index the first time. Hopefully I will not run into anymore road blocks. I would appreciate feedback o

 This shutter and especially the aperture mechanism are not usually lubed, but run dry. If yours do not, they are most probably not clean enough. Although I also use isopropyl my favourite cleaning agent is lighter fluid, because whenever some resid

Thanks Werner for convincing me the apeture and shutter were not really clean despite all the Ronsonol etc. I am in a commercial printing/digital imaging enviroment. I spied a gallon can of commercial anti-static film cleaner called

 There is a needle-trap light meter mechanism under the top cap of the camera. In broad daylight resistance of the LDR (CdS cell, Electric Eye, etc) is low, with a battery installed the needle of the meter will incline towards the end of the meter d

 Well if I am reading you right the meter assembly itself has enough mechanical power to drive the apeture directly via linkage.I guess that's my concept of the solenoid. I can see where that entire apeture mechanism must be very free!
 
I find my

 What you assume about the power of the meter is not right!  
All I am saying is that the meter needle travel allows a certain aperture to form when you push the button by making the mechanism align and stop at the right point, that's all.

 Thanks for a better understanding of the Auto Apeture. It did seem unlikely there would be enough leverage to affect the apeture directly.
 
I have some good news on the electricals. It was all dead but I fixed it by seperating the halves of the bat

 I do not know of a third pin. As usual among tinkerers you will somehow have to find a solution and then tend to like this camera dearly, not the least because you are the one who brought it back to life.  
Successful repair attempts are always proof

 There is a third hole in the brass plate. It seems to fit right over the hole for the main self-timer post (adjacent to the self-timer hole the shutter speen indent spring uses)and is the same diameter. Too bad the hole is occupied. My other thought invo

Am a devotee of the Konica Auto S-2 as well, and have several. Having found several mint cameras at a low cost on internet, several had the sensor wires sheared off as well. Have perfected the repairs, but have never been able to find a source for t

This page (and the next) has some wire listed. I don't know how this wire is measured, but could be worth a look.

Have found the perfect replacement wires for sheared off wires on the Konica Auto S-2 rangefinder. Cut open a USB cable used for printer and discovered that the wires inside are perfect replacements. However, am still looking for a slow speed escapement
