Space Mission by Williams 1976, seems to play OK except when ball lands in either bonus pocket score keeps running indef. and ball will not eject onto PF. I lifted PF with power off and saw no stuck coils or leaf switches, both bonus kickout mechs are free, not stiff or stuck, no appearances or smells of burnt coils or wires. Have not opened up top cabinet yet. Game played OK before this incident. This is my first venture into pins and forums of any kind so please forgive my errors in protocol, I'm older than the machine, I would appreciate any help in tracking down this problem.

I'll get right on that, let you know what happens..THANKS
