Hi all , I'm not to electronically inclined so I really can use some help . I have a chapion pub machine when I hit the ball up the middle at the heavy bag it only works intermittently. I checked all the wires and connections I think everything looks good.
When I go into the test menu and I do a single switch test, the switch does not close. The switch matrix in the manual looks different then the switch matrix in the game.
There are a lot of switches that are closed that are supposed to be open and vice versa. When I traced The wire back to the CPU board I noticed that it was plugged into the wrong socket. It was supposed to be plugged into J206 but it was plugged into J207. In the manual it says J207 not used I'm not sure if this could have damaged the board. Thanks for your help image.jpgimage.jpgimage.jpgimage.jpg

Thanks I'm going to do that.
