I checked, the 3PDT IN and OUT wires are well connected to the TIP so it’s good.
I inserted a jack on each side and I have a contact between the TIP of my catches and the tips of the jack cables.
I followed Barry’s circuit this morning for Bypass continuity and everything looked good …
I will insist and start testing again tonight or tomorrow, the bypass should at least work since no component is solicity!
I must have missed something.
