The Score Reels Were A MESS On This Chicago Coin RIVIERA Pinball Machine..

Joe’s Classic Video Games walks through repairing a Chicago Coin Riviera pinball machine that failed to start because its score reels didn't return to zero. He cleans and re-greases the reels, explains the cam/contact mechanism that signals zero, traces the relay logic (including a missing end-of-stroke switch on the 100-point reel), and fixes a misadjusted guide bracket causing reel play. The video is a detailed electromechanical repair tutorial with no industry news.
