[Hectic]

okay so i finally got my gun rebuilt the other week and took it out to a game last week it was a lil chilly so the hop up wasnt working so i didnt use it. However the other day i was going to plink with it to make sure the hop worked in warmer weather it shot okay for a while then it randomly shot without the trigger being pulled.
Then it would shoot going from safe to semi then wouldnt work with the trigger pulled but would agin going from safe to semi on its own.
Its a v2 lonex shell with a merf3.2 with a 2 signal wire setup.
When i first built it i noticed the wires became a lil pinched from the small exit hole in the back and from some pin on the top of the shell that sticks into the wire channel so i filed those bits down to avoid damage to the wires but i think there was alrdy some damage done. Is this likely a short in the wires causing this?
