well when i turn the game on the knocker goes crazy and says drop target coil is bad.any ideas on why i keep getting this message.thanks my thoughts maybe the doided on the coil is bad.havnt worked on to many data east
it's possible the switch that registers if the coil is down is broken/stuck
therefor the game thinks the target is always down so the coil is broken..
so go in selftests, and test both - switch and coil and see which one doesn't work
