where should I start to fix a Konica Auto S2 light meter? I have cleaned the battery contacts, no sign of corrosion in the battery compartment. The light meter shows no sign of life.

thanks

The test switch in the battery compartment is often a hidden source of problems. You may have to take the battery holder out to get to the piece that causes problems.

Other sources of problems are bad wiring, bad CDS cell, and broken contacts in the meter itself. Check for continuity in all the wires and check to see if the CDS cell changes resistance with changes in light.

With this camera the chances that the meter (-coil) itself is ok although it seems to be broken are not too bad. If, for example, inexperienced tinkerers have wrongly assembled it, it is blocked from responding to light and it just looks broken. You have to be extra careful when inspecting the meter with the transparent plastic cover off, especially the retracting coil springs are awfully delicate: if you mangle them or otherwise misbend them, your repair attempt will come to a sudden end.

I would start with the battery holder, as Dan suggests. Even though the compartment looks clean, there are hidden contacts inside it that are prone to corrosion.

Remove the battery compartment, turn it upside down and remove the two screws that are on the underside. The compartment will split in two and most likely the source of corrosion will be immediately visible.

The usual caveat - remember where all the contacts and wires came from.....
