I recently had the same problem on my Pool Sharks. Also a system 11 game. The kick out solenoid is part of the "special solenoids" circuit (yes that's what Bally called them haha). The pops, kickout holes, outlane kicker, and shooter lane solenoid were all controlled by a 24 VDC DPDT relay that burned up. It's a clear cube on the power driver board. Look to see if it's melted and or just making a clicking noise. Mine was visibly partially melted and just clicking trying to advance a ball in the trough.
