I guess this has happened to many HP-41CV users before...
Mine has suffered total corrosion in the golden contacts that connect the battery holder to the flexible circuit board. In my calculator, the corrosion has totally disolved the golden traces for a distance of maybe half an inch (1 cm) from the contact point with the battery. I have temporally placed a couple of thin wires making contact to the continuation of the circuit traces but if I remove the battery holder or slightly bump the calculator, the circuit opens. Does anyone solved this problem in a better manner?
