My Miami Beach has multiple modifications to its score disc wiring. The mods involve score disc lugs related to game proportioning (connections between score disc and mixer #2) and score steps (connections between score disc and spotting disc). I believe I know how to correct most of the mods, but there are several that I can’t figure out. It doesn’t help that the 43-3 wire shown in the user manual doesn’t appear on the schematic. If someone has got a Miami Beach and would be willing to do a few continuity checks to confirm my guesses and solve several puzzles, it would be a huge favor.
