Interesting Failure Mode: Morini CM84 Electronic Free Pistol
Posted: Sun Jun 21, 2015 5:24 pm
Just a heads up for folks. I put a new battery in my pistol a few days ago, and it tested fine. I went to a match today, and after 10 sighters and 7 record shots, it stopped firing. It took me a while to figure out that it was the pistol & not me. I declared a disabled pistol, and popped the battery cover off. The front end of the battery had shifted upwards just enough that it was no longer making contact. i popped it back in place, and finished the match with no further battery issues.
The 15V battery I was using is a round "Exell" brand, which may not have as much support as the older squarish ones. If you are in doubt (as I was a few times later in the match), you can check that the battery is connected by pressing the test button. If the LED doesn't light up, you have a problem. I've been shooting this pistol for about 20 years, and never had an issue like this before. When I got home, I took a look inside, and at least on my pistol, there is nothing to block the front end of the battery from shifting upwards. I may see if I can figure out a way to do that with a piece of plastic or foam to avoid any chance of this happening again in the future.
