Ok, so I have been having a bunch of problems with my gun, the latest being the gun firing without pulling the trigger. I have it hooked up to a homemade mosfet. I opened up the gearbox and checked the trigger contacts. No archs whatsoever. I even took out the little piece of the trigger contact that slides back and forth, and also the side plate that holds the one contact. I hooked it up to a motor outside the gearbox, connected the battery, and the motor turned on. So after inspection, I concluded that it had nothing to do with anything inside the gearbox. I then proceeded to take apart the mosfet, and build a brand new one from scratch. After putting it all together, the same thing happened, and the gun fired when on safe. This is really bugging me. When I first installed the first mosfet, everything worked fine and now all of a sudden its not working. I appreciate all help, thanks!
