It seemed to me that the contacts were a little wonky, one wasn't quite aligned right. (Aha!, I thought) I cleaned the contacts and gently nudged the errant contact back in line but, still, no luck.
I'm getting same respone (ie, none) from the light meter. It rests in the red zone below 16.
Any other thoughts? This is so frustrating - it was working fine when I last used it years ago. I think the only insult it has received has been in the form of neglect. It has been in a camera bag, etc.
