My first post here and hoping to get some advice.
Steps already taken.
1) removed battery
2) vinegar and toothbrush to neutralize and clean corrosion followed by rinse and dry.
3) continuity check on several traces. Definitely have at least one jumpers to do.
4) tested on bench
5) Researched some mvs repair logs.
Need to do or opinions.
1) Is there a schematic for this board? I know at least part of the issue is with neo-zmc2 going to neo257s. Would be nice to just verify chip pin to chip pin versus tracing all the through holes.
2) my test lead on DMM are almost too big to test these tiny pin chips. any recommendations for now and future. Super mini clips?
3) Here is link to high res pic of at least the one bad trace I have. You can see the neo-zmc2 pads and legs don't look great but I would hate to remove this damn thing. Looks to be a super pain in the ass.

3.5) if the corrosion is neutralized and I get it working is it even worth cleaning up further?
4.) Lastly, should I just jumper chip pin to chip pin or chip pin to closest good through hole of trace?
