I have 6 buttons with you as well. And I am getting a metering error. So lucky for me I have another machine that works so eventually after trying to repair I changed boards to different machines. Both had the same results. The broken board game says metering error, and the good board game works in both cabinets. So in turn, it’s a board level problem. I replaced the battery as the original was from the 80s and the machine still has the error.
I have 6 buttons just like you do. And even when I get it into the “1†mode like it says and press all the reset buttons, only 2 actually labeled as reset... it still does not reset the machine... time started keeping track after I replaced the battery.
Any suggestions would help us greatly!
Thanks
Sam
