Solution 1: (Thanks to: John)

I just got a used Nimslo from a friend which would not fire. It turned out that the battery contact was not providing enough pressure against the cells (and the cover).

Solution 2: (Thanks to: Marty Hewes)

I had one that sounded fine but didn't expose. After prodding around with a voltmeter while referring to the schematic in the Nimslo book from Reel-3D, I found grunge on some "switch" contacts inside. The "switch" was made up of a wire that made contact with a post inside. A little rubbing alcohol on a Q-tip cleaned it right up.
