Quoted from maestro:I misunderstood the original post and thought you meant they registered in test. It appears you meant the coils work in test though not the switches. My miss.
However bad caps can cause all kinds of issues. If you're going to be having old Bally games around then get you a bag of those caps. Even though all is working I'd go ahead and put one on the switch that is missing one.
Yup, I replace ALL caps & repin ALL connectors on that era Bally pins. I was chasing ghost farts on my Mr & Mrs pacman pin until I did this. Also check all switch diodes for broken solder joints - I had one that was intermittent & was a bitch to find.
