counter force gottlieb system 80, intermittant scoring
I have a gottlieb system 80 Counter Force that some times will score 1k points over andover randomly during game for a bit then quit. So far I have not been able to reproduce this malfunction in the switch test. As far as I can tell the pop bumper are the only way to receive 1k points each. There switches seem to not be adjusted to close buy any stretch of the imagination. Popbumper misfires are not accompnnying the scoring issues. Of course it did this a little bit yesterday then stopped!
Possible connections issuess to strobe/return lines? Possible bad diode for switch matrix wiring???
Ideas on what to check. It is an intermittant problem.
