Quoted from TopMoose:Once again I've completely overthought the problem - you're absolutely right, a backing blade was shorting the rollover. I bent it up a tiny bit and now everything is perfect!
On the plus side, I'm getting better at reading schematics and learning about EM logic.
My next project is upgrading the flippers. Is there a trick to removing the roll pins in the links or do I just need to get that $8 tool from PBR?
or buy the plunger/links already assembled from PBR, time saver for sure.
