I have a Chicago Electric dual mig-151 that the constantly feeding wire with out pressing the button the gun. I took the gun apart and didn't see any signs of shorting or touching each other. I traced the wires to the circuit board, In so doing i unplugged both wires from the gun and now I cannot figure out where they go. Looking at the wiring schematics one goes to back of the machine, I dont know where the other one goes. If you have one, can you please attach a picture for me? Thanks
