I just rewired a German epee and I am testing it before putting in the tip. I plugged the weapon into a test box and stuck a metal screwdriver down the barrel to test if it is conducting properly. When the screwdriver is perfectly down the middle of the barrel, I get a green light as desired. But if the screwdriver touches the sides of the barrel at all, I get a red light (grounding(?)). I then took a german tip and an epee spring and compressed them in the barrel without tip screws. 80% of the time I would get the green light as desired, but the other 20% I would get at least a flickering, dimmish red light. Did I somehow crush the wire when rewiring this or is it a simpler problem? Thank you.
