The up/down ramp posts were not working on this game.
Zaccaria used some heavy duty coils for these posts and even put heat sinks on the individual transistors but even that was not enough to keep the game from blowing them out.

After replacing the two transistors both posts worked in solenoid test but the the left one was acting up during game play and would stay down. Upon closer inspection it was actually activating twice very quickly (under a second) The second activation was lowering the ramp so it made it appear that it was never fully raised. There is a switch under the playfield that indicates whether the ramp is up or down. This switch was stuck closed so the game thought the ramp was always down, thus the error. Adjusting this switch fixed the problem.
