Pop bumpers do not show in switch test: pull the ring down to test them

On this game the pop bumper spoon switch fires the coil directly and is not in the switch matrix, so hitting the skirt does nothing in switch test. The scoring switch closes only when the coil pulls the ring down: with the game in switch test, pull each ring down by hand and the bumper's switch number should show. Also remember the game needs all three balls in the trough (and credits) before it will start.
