Hey, wondering if you guys had any clues on this. Re-wiring a Senheiser wireless mic, have had to go from the ground up on this repair. The two wire in the picture go to the lower two solder points on the capsule. However I've forgotten which was hot and which was ground. I initially marked the ground one but it's come when I initially attempted to re-solder the original wires and I neglected to re-mark it. The manufacturer has marked one of the two upper solder points with a blue dot. Does anybody know whether that dot would indicate hot or ground? Hoping that it's a commonly used indicator!
