My trap door will not test. In test mode, I hear a thunk cycling, but no door motion. When I boot up in test mode, it says check sw 76 which is trap door closed switch. I checked the sw with a ohm meter, and it works. No broken wires. If you manaully move the solonoid plunger, the trap door locks open. When you turn on the game it slams shut and gives the test error(sw 76). Any ideas. Should I test it with the playfield up to see what it is mechanically doing? not sure on this one.
