cool, you the man. On no noise. You put motor, wires, but also the motor connectors. if the guns been takin down a few times they get loose enough not to make contact. If so you just need to crimp down on them a little with some pliers. Or the connectors break where they're bent. If that happens, I have some gold plated replacements that I could install for a small fee :D
