It moves very well, yes.

Very helpful - thanks.

I see what you are saying, as well as the link George provided above. This makes sense. I'm gonna try this, and jut hot wiring the meter as well.

I picked up a 35rc recently. Cleaned the finder and good as new, almost. Got it cheap because of a dented filter ring. When I got it I found that the filter ring is recessed, making it look almost impossible the remove the dent without traumatic disassembly of the lens.
I wonder if it's worth the potential trouble or should I just admit that I rarely use filters on a RF camera anyway?

I would leave it alone personally. I don't like to mess with glass.

New pics added showing removal of the battery compartment and the meter. I also added some showing closeups of the rangefinder and film advance.
The screw holding the contact and the wire on the battery compartment was heavily corroded, so I got a new screw and nut today that should work. I drilled the old one out yesterday because the screwhead was stripped.
For those that try, it is a bit difficult to removed the battery compartment and you may dislodged the wire on the bottom (white wire in pics.) It's easy enough to put back on, so it's not a really big deal, but do it carefully nonetheless.
I think the my meter looks pretty good and the needle moves freely. I removed it to check it out and resoldered the connection yesterday. (Black wire in pics.) I am going to try and replace the battery compartment today and see if I can get any power to the meter. If all this doesn't work, I'll be at a deadend and will use it without the meter, unless I get some other suggestions.

Rob, Any luck?

Nope, dead end right now. Not sure why no power. It may be something internal I can't get too. The connections look good at the battery and the meter, and the meter looks good.

I did a Konica recently and the connection at the CDS cell was bad. Since this one appears to have been wet, all the contacts are suspect. You may just have to break out the hand held meter. If you had a meter you could probably test the CDS cell.
Good luck,
George

I have a meter - do you know how to test the CDS?

Can you find the leads going to the CDS? If so, install the battery, then put one lead from you meter on the negative side from the battery holder and the other on each side of the CDS. Make sure you can read 1.5 volts on your meter for DC. You should have different readings from each side, since the CDS acts as a variable resistor controlled by light. I'm out of town and won't be back to until the 16th so I can't look at my notes or diagrahms. Have you tested the meter to see if it is getting any voltage? That is easy since the meter is in the bottom close to battery compartment. I think the trick will be to get a battery cover on to drive the voltage. I have in the past used two cords with alligator clips to attach to a battery with wire soldered on both positive and negative so i can attach the clips. This would be easier than disassembling the lens to get at the meter. If the meter is not getting any voltage it is probably a connection at the CDS. I've never had to replace a CDS but I have had to re-solder connections.
Hope this helps.

Hi Rob, any news ? I'm on beginning of path (no juice) and see future with Sunny16 and handheld meter.
btw, great sequence of internals.
Oh, I just understood how meter activity translates to aperture setting - that little needle has to move. On mine RC it doesn't. Black wire seems strong, but I'm not sure if meter is operable, and here I have to bring multimeter home.
....
Now connected negative from battery to point where black wire connects to meter. Needle jumps! But not when white wire connected to battery...it means it need to check CdS...and at least point where second end of white wire comes out - is it at CdS in lens barrel, anyone ?

BTGC,
Did you look at Rick Oleson's diagrams? They pretty much let me through my restoral. I have done a lot of cameras lately and many of that vintage have wires on the battery, or meter that look good but with a gentle tug, they come off. The corrosion seems to hold them in place but the contact is no longer there.
Look forward to hearing your progress reports.

George, thanks on pointing to Rick's resource, will check - completely dropped out of mind.
When I wrote before, I touched contact on meter with screwdriver - it's good and connection were made to wire before soldering point, so this one shouldn't be problem. Connecting battery with CdS throws needle left. So what's between - I think "A" mode switch, so will check diagrams.

I'm still kinda stuck. The needle moves freely on my meter and the meter looks remarkably good, but I'm having difficulty determining if it actually works and if juice is getting to it. Next time I work on it I'm going to investigate the CDS.

I ordered some foam to reseal my Oly from Jon Goodman tonight (interslice on ebay). Of course, he sent me a pdf version of instructions on how to do the work on the Oly 35RC about 5 mins after my order. Thanks Jon! He said to say hello to all of you that know him.
I also ordered some new camera leather from www.cameraleather.com, but I'm not going to tell you what kind until I post the pics, but it ain't black!

Rob,
Looking forward to see the results. Seems like the electronics on these are usually the worst part. I'll bet the soldered joint on the CDS is bad if the meter reacts to any voltage. Good luck!

Well, no luck getting the meter to work, but I resealed and reskinned her:

looks very neat mate.

Sometimes you just have to take what you have and make the best of it. The re-skin looks good and you can still use it. Good work!
