Hi Pete,
did you get the schematics page from DAG? Any chance there is a higher resolution version or even more pages? I’ve been trying to find a service manual for a while, with no success.
How did you get the circuit board out? I’ve been halfway I guess, but wasn’t able to remove the matte black framing totally. Did you have to remove the shutter? Or even clip the wiring?
My CL has some pretty finicky wiring and always drops out at some point during the light-meter calibration process. Probably a loose contact or some broken wire. I’m also afraid the trimming-resistors will give up their ghost while trying to calibrate too many times.
I’d be thankful for any hints what you have done to your CL and the steps you took. Looks like you redid all the wiring?
All the best,
Alex
