I'm having trouble with my flippers, they will stick in the up position after you hit the button and only go back down if you hit the button a couple times, sometimes I have to turn it off to cut the power to the coil. I have replaced the complete flipper assembly for both flippers, wiring is correct but I'm not sure on how to adjust the EOS switch, also I thought I read something about relay not working and a opto switch. can anyone offer some suggestions.
