so the bottom 3 terminals in the pic are for the monitor as I understand it. so the Ground wires on the JAMMA harness go to the COM on the power supply? and if so, which COM as there are 2 of them? Here is a pic of the PS in question.. http://i4.photobucket.com/albums/y145/pharoah007/DSC04221.jpg thanks everyone. :cheers: |

hummm no replies... Is this info in the FAQ or a sticky?? I have been looking and have not come across it. Thanks all |

1. Yes, GND goes to COM. 2. Pick one. I'd use a multimeter to check that they are the same, but I imagine they are. |

Usually, you just wire up the 4 Ground next to the power pins on a Jamma connector to the Power Supply. Depending how what I had available, I'd wire it up using 1 terminal or both terminals. Read this to learn about the other grounds: http://therealbobroberts.net/jh.html |
