AEG won't shoot, no noise.
 

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.

When you say the battery fell out did it fall out of the gun and tug on the wires and then get free from the plug and hit the ground?
Sounds like a lack of power either from a bad battery or a bad connection somewhere.

Bad trigger contacts maybe?

I meant that the wires connected to the gearbox fell out so like from the battery all the way up to the wire that connected to the gearbox.

Be more specific.

There's a difference between an exposed wire where the wire fell out of its housing compartment, and a wire that got tugged off and disconnected from the gearbox.

Are you trying to say that the battery fell out of its housing and that tugged ALL the wires out and disconnected it from the gearbox?

going to say trigger contacts are carbonized/dirty/burned.

Pictures?

left a battery in it and cleaned some gunk out of the outer gearbox and when i came back it was shooting but the battery was burning hot. I'm concerned about why the battery would be burning hot when it was just idling for a few hours, anyone know what's up? the gun seems to be fine now, can fire full auto and semi and everything and is very responsive. It's just that the battery was so hot as if it were overcharged when all it was doing was sitting connected to the gearbox

btw thanks, it was the trigger contacts!

shorting wires.. something is pinched or making contact.

What does that mean? Sorry for the dumb question.

It means that there's a wire somewhere that has the protective rubber pinched and made a hole in it. Electrical tape will fix that, if you can find where it's pinched that is.

Thanks so much! I managed to find the damage and it seems to be at 100% right now, will try it out at the field this weekend but from testing at home everything seems fine.

This means you prolly need a gun doc.
