After doing some work on my Nugent yesterday, the game play had some scoring issues. The game would start fine, but the moment the ball was in play, I was being awarded many more points than I should have been. Further to that, certain targets failed to register and some roll overs would cause the lights to flicker.
I took the glass off, started a new game and hit each target with my finger. I narrowed the issue down to the three roll overs at the top of the play field and the static target. All other targets and roll overs were functioning fine.
I then put the game into test mode and found that switch #4 was stuck. Looking at the Nugent manual. Switch #4 was the left and right roll overs at the top of the play field. Ok, so getting somewhere.
