Hello everyone, New to pinside and a new first time pinball machine owner. I recently purchased a functional Knockout machine with a couple of issues I would like to address. The first is that I would like to return it to coin op. Really have no idea how to go about this and was hoping for some advice....please....Also the 2 nd player function is not adding correctly. I do not have a schematic and know I will need if anyone can direct me on where to obtain one? Any help or advice will be greatly appreciated. Thanks in advance, George
