Got the shutter working by naphtha. Next up is focusing distance and the light meter. I am reading the archives for how to make a makeshift collimator and I am going to try that now. But the meter is not responding. Since I have the CdS housing ring off, I have connected at 15 K Ohm resistor to the two wires (blue and black) that go to the sensor. This resistance should show some deflection, the resistance of the CdS seems to vary with light and the 15 K value falls within that range. Battery check gives the deflection though. What else should I check to see why the meter is not responding to light? Thanks.
