And be sure your new battery is actually a good new battery. I recently had battery problems with my Mamiya and discovered my new batteries were old inventory and were dead when purchased.

I dry fired it several times before the problem occurred, it had a good battery but went and bought another one in hope. Thanks for suggestions.
