Unknown component fell out of iPod when looking at the battery.
I recently purchased a real lemon 1st gen Ipod Touch 16 GB, off ebay due to some tricky fine print. Instead of just eating the purchase I decided to attempt some trouble shooting and repair. The first thing that I was going to attempt to fix was changing the battery as the unit would not charge properly, however a black wire about 3" in length with soder on one side and some kind of angled connection on the other fell out of the I pod. I am inserting a image below. Any help would be greatly appreciated I am new to working on these small scale electronics.
Sorry about the quality on the second picture I can take a better one if needed.
