bought a hollywood heat pinball machine but it doesnt save the scores. it doesnt look like theres any battery installed although there is a little sticker that says “do not populate batt with nvram loaded”.. so i bought a battery pack to mount off of the circuit board, do i just need to solder the pos and neg to where it says + - on the board? am i doing this right? dont want to mess up my circuit board.
