Need a little help. Brand new owner here, and I was doing some routine cleaning/maintenance one would do on a newly acquired machine. I've had the playfield up and down numerous times and the backbox folded up and down. The game was working 100% before my cleaning. Now, upon startup, I'm getting about 5 switch errors, ALL optos. 8m sure it's not 5 switches. Which board or fuse is common to the optics? Oh also it says magnet unload error. Thanks!
EDIT: Found an unplugged connector in the backbox. All is well!
