Quoted from n0s4atu:
It registered dropping it in the mystery hole, but the left side magnet pocket the optos aren't registering.
Inspect that Mystery switch closely. It's the last switch on that column and it's the only non-opto switch on that column. One lug should have two green and black wires attached. One to the CPU, one to the opto board. (going by the manual, my game is on location)
I think you guys would do better posting problems in the tech section. It's hard to help folks in this thread when 2 or 3 problems are being posted about at the same time. Plus, there's some awesome techs out there that don't own a BSD, but are very familiar with WPC problems.
