carefully look through the forum... i know there are pics somewhere. It's a bit tricky, but i've repaired them numerous times. You just need a soldering iron.
If you carefully look at the pcb where the copper wires remaining are soldered you will see that one wire is soldered to location marked L for left beside that two wires are soldered to battery negative terminals ( usually a bigger blob joining two pads together ) and the next spot over should say R for right resoldering them is rather easy. and as far as making sure which one is which if both are off the left or right side i have noticed it doesnt matter which one one goes where just have to be L + and B - i believe.
