Hi everyone,
Here's my situation: I have an old JAMMA cabinet connected to a JPAC connected to my PC. Everything was running hunky-dorey until I decided that since I wasn't using the old power supply and it was just taking up space inside the cabinet where I could mount my computer. I'd already disconnected the power supply before I hooked up the JPAC, so I figured it wasn't of any use anyway. In my fervor to pull out all the old stuff, I didn't realize that I had disconnected the ground wires to the the JAMMA!! (I'm really new at all of this and obviously kinda stupid). When I hooked the ungrounded JAMMA/Jpac back to my PC it went nuts! Thankfully I had set a restore point on my PC so all is well with that, but now I have no clue where to put those ground wires. I'm assuming I should just put the old power supply back in there and hook it up like it was before, but of course I didn't pay any attention to what I was doing. What do I need to connect these ground wires to in order to make this work properly?
