I just started getting three "adjust switch" messages on my F-14 machine. It's saying to adjust switch 28--pop bumper, 57--left kicker and 58--right kicker. I've opened the machine and all switches appear to be working and I don't see any loose wires. Any suggestions for what to do next? I've seen the switch matrix table in the manual, but don't know what that corresponds to inside the machine.

Check the rows and columns on the matrix table for those switches then check all the other switches on their rows and column in "switch edge test". Look for broken off wires and/or diodes.

Thanks. All other switches seem to be registering in the switch edge test. couldn't see any broken wires or diodes.

The switches that control those solenoids are not in the switch matrix. The pop bumpers and slings each have an additional switch which is "allowed to close" when the solenoid fires. It's the second switch that the game is complaining about. You may notice that there is no sound or points scored when you hit the pop bumper or slings. The fix is to adjust the switches so that they close when the solenoid plunger is pulled in.

I just started getting the exact same 3 adjust sw messages on my F-14. Game was playing error free and then Adjust switch 28 , 57, 58 showed up.together. Neither sling or pop bumper solonoids are firing. These switches are not being read during switch edge test. I see no broken wires.

Did you resolve yours?

Check fuse F2 on the power supply board.

Update. When I finally had time to look. Mine was the under playfield 2.5A slow blow fuse. It was confusing though because the fuse was not completely blown. I could read 32V at the solonoids but couldn't make them fire by grounding the control side. There are 2 under playfield fuses on my game. This one was hidden upper end.
