Quoted from JReedie:Along side this is having plenty of scoring issues which I think is associated with this indicator mech. Scoring for that seems to be all over the place.
The scorecard gives a hint that scoring of the indicator varies "mysteriously" but only scores when you move the pointer. The BS relay tries to stay in sync with the indicator target. When you move the indicator to a different pad, they are out of sync, and some arcane circuitry is involved for the BS relay to search for the new location along the way. It scores 50 per cycle of the score motor while searching, then more (plus spotting the number) when it finds the new location. There is deliberate scrambling of the 10 wires that connect the 10 segments on the indicator to the 10 segments on BS, so a short move of the indicator may require a long search, and vice versa.
A good test at this point would be to start a game with the glass off, ensure that all numbers 1-10 are UNspotted, then manually move the indicator to each number and see if it gets spotted. You may find that your BS relay has trouble finding some numbers. When moving the indicator manually, move it to the center of each segment, so that you are not causing any high-resistance edge contacts.
