I don't believe there is a stepper unit apart from the 0-9 unit which never re-sets. ..... I'm obviously missing something here that should be 'leaping out at me'. .... It's at times like this that I'm reminded just how limited my true understanding of these machines really is. As I say ... if it's not in the Hank De Jaeger pinball repair book then I'm usually stumped. Any other hints will be tried.
