Have an issue with the knocker and credit wheel. There are three ways to get a replay, score, specials, and points on a target. The knocker fires and the credit wheel advances on the target,occasionally on the Specials, nothing on score. Looking at the schematics it looks like the knocker and credit unit go through the 26th stepper Free Play unit. Just can't figure out what to look for. Thoughts?
