I've been troubleshooting this and I'm stumped now. I've rolled over all the aces to light all four lights on the horseshoe. When the Horseshoe rollover gets triggered it's scores 30,000 points and the next time it's scores 40,000 like it should and this cycle repeats perfectly until the end of time. I narrowed it down to the ace of diamonds. I've traced the paths where the diamond relay is between motor switch 2d and the rollover relay switch and I get continuity. I've also traced where it goes "to br-b at c2" and switches 3d, 4d and 5e seem to work fine. See attached photos for the paths I'm referring to. What am I missing? I'd be grateful for any help. Thank you.
