In the resting position the EOS switch should be closed as previous poster stated. When you push the plunger into the coil the EOS switch should open when the plunger is just about or fully pushed into the coil. Check the contacts on the EOS and make sure they are clean and touching each other when not activated. Make sure no wires broke off of the coil or EOS.
If the game was playing other than a weak flipper before think of what else you did. Is the score motor in the right position? Try turning the motor 1/3 around and try starting it. If nothing happens rotate 1/3 more and try again. If nothing happens again try resetting the bank manually.
