Title: Namco coin acceptor is a butthead Post by: legoman on May 28, 2016, 02:57:30 am Hey gang, this has been driving me nuts for a couple weeks so I thought I'd see if you have any advice. I have a Namco Mario Kart Arcade GP2 cabinet (very cool game, by the way, you can race as a Tamagotchi?) whose coin acceptor was disabled at some point. I'd like to set it on coin play, but I get the feeling something's missing. I can get it to coin up just fine in JAMMA test mode so I know I have the correct wires, but in actual game mode it will only coin up intermittently, almost at random. From my research I figure it either has something to to with a JVS converter or possibly the brand of coin mech called a MEI Cashflow. I bought a Cashflow just in case, but I feel like it's a dead end. Anyone ever had this sort of problem with a Namco cabinet before? Sounds like it can happen with Naomi cabinets too, but I've never read about anyone finding a solution.

I could wire the service button to the coin switch, but the button press from a coin flying through there isn't long enough to register a service credit. Resistors maybe?
