There's also some other thing that you can short out to reset it if there's graphic artifacts. 25V, but you'll have to test it for yourself.

you can probably get away with 5.05-5.10 at the logic. once you know what the differential is you can adjust the voltage accordingly. measure at the power supply first, then measure at an IC. by virtue of the wiring running through a filter board and then powering like 5 different boards you'll observe a lot of voltage loss. you can't do it at the roms as they have a different pinout than normal, but there's some smaller ICs that you can get voltage readings at. that's how I did it for a couple years until I discovered the art of measuring at ICs. You can blindly change the voltage and hope you get it right. whether they go low or high is anyone's guess.

where the power supplies are mounted, you get a lot of people that bang their feet on the floor of the game, and I gather that means the voltage adjustments on the power supplies will move. I had that happen a lot when we had a Daytona twin.
