I was adjusting some of the 10 point switches on my Jacks Open as they weren't quite close enough. These are all of the playfield switches activated by the rubbers. Once I finished, the switches no longer do anything after ejecting a ball. The 10 point relay will engage and release fine when manually activated. Everything else, incluing rollovers and drop targets, works fine. I checked all of the switches and none seem to be touching when at rest. Any ideas what could cause all of these switches to quit at once? Thanks in advance for your help.
