Since your camera had not been used in a long time there is a chance that some thin layer oxide is covering all the contacts.
Move the ASA lever/dial back and forth several times, same for the speed dial, and exercise the camera for a few hundred frames.
Then check again, sometimes it works.
Originally posted by Greg M While watching television last night, I decided to scrub the battery terminal and the battery cover with a pencil eraser. I took about half an hour of slowly rubbing on the spring terminal, blew it out with canned air, crossed my fingers and put in fresh batteries. Lights came on, the battery check worked, and the needle moved for exposure indicator.
ONE MORE QUESTION. I put the Pentax 800-200 mm f4.5 on and noticed that at ASA 400 the automatic exposure button reads about three shutter speeds below the meter reading on my Gossen. The selector dial is very gummy and hardly moves. The asa selector lever is at 400. Outdoor meter reading stay about 1/60 at f16 in bright sunlight.
