The TOM I'm working on has some strange issues with it's trunk. Opto's all work, and it has a new metal interrupter. But during trunk tests, I'm getting errors except for one face on the trunk. The gap in the interrupter does not line up with the opts for all faces.
Regardless of the mis-allignment, the trunk generally seems to work during game play (except once in a while where it's slightly off, hence the problem).
I've read the other articles on Pinside, but don't see anything that matches this behavior. Anyone have an idea what to look at?
