My Ship Ahoy stopped playing and scoring in the middle of a game and did not eject the ball after draining. After restarting the power, the coinslot and backbox graphics, scorebox, ball number and Tilt, but not the Game Over, lights were lit. Trying to start a new game did none of the usual things, like resetting the ball count, zeroing the scoring reels, spinning the motor, lighting the playfield, ejecting the ball, activating the flippers, etc. With the playfield up, all of the fuses and voltages seemed fine and the only things I saw happen with a power restart were the TX Tilt relay and coin slot coil energizing. I gave up, made dinner then went back to check everything I could think of, but nothing seemed wrong. Even though the top motor pin was under one of the three level D switches, I decided to spin the motor a third turn to put the pin under the next switch. When I turned on the power, the machine started right up and played perfectly thereafter.
Can someone explain what might have happened?
