I have an ECHO 1 M14. I've had the gun for about a year and it was working fine on Sunday when I went. When I went again a few days later it started acting up a few minutes in (the gun would stall when firing in semi so I switched it to full auto to clear it and it was fine) and it repeated this process a few times. A minute later the battery fell out all the way from the end where it connects to the gearbox, I connect it again and the gun won't shoot at all now, no noise, nothing.

When I'm pulling the trigger and put my head up real close to the gear box I hear a very soft static noise by the motor for about a second every time I pull the trigger back but that is all the sound it makes, and it is very, very quiet.
I've tried 5 different batteries, not sure where to go from here.

Also, I had the gun worked on in the past, there is no longer a fuse box inside of the gun and I have been running it that way for over a year, just putting it out there in case that could be a factor.

EDIT: After pulling the trigger for a while the static sound from the motor got louder and louder until it finally shot once, then back to quiet and nothing.
