Pretty amazing feat. I loved reading these entries every morning with my coffee. I might just start over with repair number one. If anything I think the most valuable thing from reading it is learning the troubleshooting patterns.
The same crap goes wrong . . . and he generally fixes it the same way. Learning those patterns as a point of reference takes a lot of the guess work out of pinball repair when a problem pops up.
