I’m rehabbing a Cross Town. I agree with MarkG’s comments on the relay bank. I can send excerpts from the schematic if you need them.
On the fan target, it sounds like it is working correctly. The target scores 10 points unless the red and yellow match up. The only time the special should be lighting is if red and yellow match up at special.
Good luck. This is a great game and once I resolve a few outstanding issues mine will be ready to go. Still have cosmetic issues but it is coming along.
