So this has been fun diagnosing, as the title implies my Dodge City is having issues.
When I hit the "Replay Button" the machine goes through it's normal startup process: lights come on, score motor runs, score reels start to reset however they do not reset back to 0 before the ball kicks out and the game starts. It will pulse 5 times then the Reset Bank engages and the game begins. Z1, Z2 relays are getting pulsed from the "SB" relay.
Apparently something is engaging the "U" relay before the scores go back to 0. So I'll just update this as I work through the issue so someone can avoid some heartache maybe.
FYI: All the score reels will stop at 0 when they get there so the run out switches appear to be in good shape.
Edit: Checked the blades on the "U" relay and everything looks good, but the relay is never pulsed. Not entirely sure what that's all about.
