Hi,I have a issue with score reels going to zero on start up.( only one and ten reel).sometimes they will not go to zero on start up.i noticed pattern .if score reels are close to zero at end of game they will zero out on start up.also a pattern of playing a half of dozen games and they will zero out then for two games they will not.i rebuilt score reels twice replacing old wires ,cleaning all switches.,but seem to think problem is before score reels in circuit.and I do not want to guess, making more problems.only diagnose and correct problem properly.any help.thank you.

Thank you Howard.i will do that and let you know my results.

Hi Howard,again thanks.the problem was bad connection at reset relay.working good now.
