So I have a new one, at least for me. I have an epee that passes Gap and resistance tests for the tip but when I do the ground test on the bell guard (on the piste) the center of the bell guard passes but as you move out to the edge of the bell guard starts registering as a valid touch. I'm going to try cleaning the socket and inside the bell guard. I suspect that corrosion is causing the issue, just barely passes near the center of the bell guard but as you add that 0.2 ohm as you move away from the center it now fails. Has anyone else seen something like this?
