We have been working on a Target Alpha that currently won't score points except for the pop bumper (100). Nothing else that scores 100 points or multiples of 100 will work. I don't know how many points the large drop target bank should score, but they don't score anything either. The light for the bonus does come on, so I don't think it's an individual switch issue. The lanes at the top and the middle also score nothing. They only make a sound when the lane is lit, but still no points.
I feel like I have checked every relay and every score motor switch, but I know there has to be an issue somewhere. Any ideas?
