I recently decided to upgrade my kit built tele to have a 4-way switch. I wired up the switch (OAK Grigsby) according to the fralin diagram. I have triple checked the switch wiring and it matches the diagram. The problems arrived when I tested the new wiring. When I put the switch in the bridge only position it works fine but I get no signal at all from any of the other switch positions. I did go through the steps to split the neck coil from the cover. Is there a short or loop somewhere that I’m not seeing or did I not ground the cover correctly?
