TECH: Williams Hot tip EM version
steppers were cleaned, switches gone through etc and all worked fine. a couple weeks later the ball count unit would not step up all the some. sometimes it will let u play ball 1 over and over 10 times or more and just never step. sometimes it will actually go to ball 2, then it will sit there a while over and over, etc. the ball count unit does reset step down correct at game start. i replaced the step up coil just in case it was flakey, and it still acts up. the ball index relay, out hole relay all switches are properly gaped and those relays work and fire properly. help!! please.
when the ball does not go to ball 2 , ball 3, etc. it is the actual ball count unit itself that is not firing. if i manually increase the unit by hand, it steps up properly.
