As the title says, my pentax 645 that I recently obtained isn't drawing power through the grip. It was missing a lithium battery, which I ordered. I tested the mechanical wind/shutter and they work. And I have some 120 film in the back (no idea what iso it is since it was already loaded when I got the camera). I've tried using 2 different sets of AA batteries and I have tried taking off and putting back on the grip and still no power to the body as far as I can tell. Tomorrow I am going to try to clean out the battery pack/grip points in case of battery acid build up.


Has anyone else had a similar issue and how did they fix it?
