Webster, NY
Quoted from pmWolf:I was SO SURE that the problem had to be with switch #18. I checked/replaced the diode, changed the switch, and re-checked everything. I tested the CPU, and it wasn't the problem...it was something on the playfield.
I took a look at every switch in column 1. (13, 14, 15, 16, 17)....because I just figured that if they were going off, that the problem had to be in that column somewhere.
Based on some great advice here...I was barking up the wrong tree. The issue was in the ROW. (Row 8).
I found the mess up at switch #58. A tiny strand of wire became frayed, and was touching a neighboring lug.
Took care of that, and everything worked out great!
Thanks again, everyone!
best post ever. just solved my self inflicted problem. movinh the outlane post i shorted the leads of that switch together causing the exact same issue. if you poked around you may have discovered the upper millions swapm standup trigger multiple switches just like the outhole switch did.
