Quoted from Dellis:What seems to be happening is that the drop target is getting a signal to drop the target again (multiple signals based on the multiple times the coil fires) when it shouldn't--as if it thinks lock is lit when it isn't
The signal to fire that coil goes through the ribbon cable that attaches between the CPU board and the driver board. Reseat that cable (both sides) or try a known good one.
The ASIC chip on the CPU board can also sometimes cause odd problems like this. Does the game have a Rottendog CPU board? If yes, you may want to remove the ASIC and inspect it for bent pins. Need a chip puller to remove it.
