Hi everyone,
I'm currently repairing my second Korg Polysix and have discovered some possible trace damage under C40. Those who change the battery for a coin cell know that C40 is often removed. Under C40 there are three tiny traces. I attached a link to a schematic photo. You'll see the red line underlining the trace I'm looking at. You'll also see the end point, but that's where I'm not sure about. Is that really the end? I tested for continuity from the start point to both the connector and another point further along. I get no audible beeps. Either that trace is completely dead, OR I'm not getting the correct end point for testing. Would anyone happen to know either what that trace is for or where the exact endpoint is? The schematics seem to indicate pin 7 of connector CN03. Thanks! - Jim
