Electric components problems
I have two issues I want to bring to you, experts and amateurs alike:
1) I found 3 9v battery cases with leakage in a bulk I bought. I disassembled them (taking away the plastic compartment and removing the metal parts) and used the usual recipe of acid+toothbrush+drying. I could remove all solid leakage but could only save one case (which now works!). The other two's metal parts still look blackened or darkened by the leakage. They are not perfectly smooth to the touch although no solid materials remain on their surface. Also the circuits directly attached to the case have also suffered and I tried to treat them the best I could, but given you can't remove them I suspect some deposits might still lurk beneath them.
Any idea why it will not work? It's been cleaned, cloth then air dried, all components put back in their right places, all contacts seem ok...
2) There was also a monorail motor in the bulk. It looks fine but it doesn't work at all... I can't find a way to open the thing and peak inside to try and fix it...
Anyone know how to pull up such a stunt? I know these motors are tough and I never came upon a broken one so I'm quite helpless...
