I have been having trouble with my KMS 105 microphone. When plugged in and held it sounds 'live'. I suspected this was a grounding issue so I opened up the microphone and discovered the green wire that connects the ground pin to the board had become detached (at the board end). The other three wires connecting to the board appear fine. They all look to be glued rather than soldered. What is the best way to reconnect the detached wire?
