Hi everybody! this is my first post here! I just got a defect mac classic II and I am in the process fixing it (at least trying to). I removed the logic board. As expected, the capacitors have leaked. But worse than that, the battery also leaked and produced some oxidation. So I unsoldered the battery support and ordered a new one (as well as a new battery and a complete set of tantalium capacitors...). The oxydation under the battery support was quite easy to clean. Some work with a magnifying glass remains to be done here: The two battery connection points are annotated with a red circle. Now the back of the logic board: My problem is that I do not see were the "-" connection goes... it is alone. Is some wire missing here ? (=totally destructed by oxidation), particularly on the back side ? Many thanks for advices!
