I'm not impressed with the Kahr 5v regulator boards. I used one on my White Water once and the issue got worse, it started resetting constantly in a loop and wouldn't even boot up properly. Removed the Kahr board and the game was back to being playable and just resetting at certain times. The fix was to follow the proper troubleshooting measures and repair the 5v supply chain.
I get the sense, now that others are having the same issue, that these kahr boards are underspecced for a few WPC games.
