I'm having a weird issue with an Iron Maiden machine I currently have in my basement. Fast moving balls seem to be knocking the flipper down a fair bit before pulsing the higher voltage, additionally they don't seem to be as difficult to push down as my Avengers right next to it. From what I can tell, it seems like all 4 flipper are affected.
I've checked the EOS switches in the Switch Test and they are all working properly from what I can tell: normally closed and then opened when the flipper is fully raised. I've checked the gapping on the switches and have tried them with a very tight gap and then with a wider one, same issue.
Does anyone have any ideas on what else I might check out?
