I’m putting the finishing touches on this Top Score that I’m about to put on the market, and I noticed today that the score-threshold feature that awards replay works on player two (all three score thresholds), but none of them work on player one.
I’m assuming from the schematic that it has to be something on either the player one 1000s unit or the player one 10,000s unit (or both).
I re-soldered to the “C“ contacts on both of those circuit boards thinking that might do it (both looked a bit dicey), but that did not work.
What else should I be looking at / testing on those reels or elsewhere?
