My dad gave me his bose soundlink color 2, claiming that the charging port was loose. I opened it up, plugged it in, probed around with a multimeter, and I can measure 5V all over the board. I wiggle the charging cable around, no change. The port looks fine: sturdy, clean contacts. I measure across the battery wires and I get 0V, so I assumed the battery was the problem. But then a few minutes later after I disconnected and re-connected the daughter board with the buttons, lights were flashing and I was reading 3.3V across the battery wires. The only logical explanation for this I could come up...

hello!
