Trying to revive an Elektra with bad acid corrosion for someone, not too experienced / confident on old Bally. I want to install a remote battery pack. I have a diode with band towards + terminal on board. But how do I actually mount the battery pack? The original blob of acid appeared to have 3 terminals, not 2.
Do I put - of battery pack to non banded end of diode, + of battery pack to - of board, and ignore the middle terminal on board?
