Got a good deal on an F-14 that needs a little work today. No battery acid damage at all and everything looks great on it.
The game boots up fine and goes into attract mode, but when you credit it up and press the start button it fires a few coils and sounds like it may be searching for a missing ball, and then it does not kick a ball out into the shooter lane and the game doesn't start. I made sure that 4 balls are loaded in the machine and inspected the trough switches to make sure they looked like they are being pressed.
First I ran the solenoid test and see that the kickers are all working that should be loading a ball into the shooter lane.
When I run the switch test I get no errors and every switch seems to be working throughout the machine except none of the 4 switches in the ball trough register at all.
All fuses in the pin tested fine and the only other thing I see physically wrong is that the right bottom flipper is burned out and doesn't work.
Anyone know what could be making the entire switch bank for the trough not work? Could one dead switch be causing them all to fail since they are daisy chained? Or could it be something further upstream?
