| Grounding - Okay to 'Split' From Ipac and Computer Power Source? |
| (1/3) > >> |
| RoninEditor:
I'm a total 'electrical noob' so hopefully this isn't a stupid question... basically, I'm grounding my pushbuttons in a daisy chain (like the Delusional vid: http://forum.arcadecontrols.com/index.php?topic=77412.0). I'm wondering if I can ground my coin slot microswitches to the computer power source ground, like, chain it to the negative of my 12v LED lights (not sure if the 12v or 5v source matters?). The reason I ask this is because, it looks like in Delusional's video that you have to keep it bouncing from one button to the next, in a straight chain vs. splitting one off into a "Y" to reach out to my coin slots. If I can just split off from my Ipac's ground, going one to the coin slot micorswitch, then the other part of the "Y" getting the rest of the buttons on one side? This would obviously be a lot easier, I'm just not sure if this is 'okay', without frying something. (Another random grounding question, the Earth Ground from my trackball...? Can I just screw that to a nut on my CP?) |

The coin switch ground should use the same ground as your buttons from the Ipac. Just make some long wires and use crimp connectors. |

Yes, as Ginsu said, ground the switch to the IPAC. Don't ground the lights though. |

Mine hasn't been properly grounded and it's been fine for 5 years now. |

Well, I did some test runs and they all work well with it ground to the black cable out of the computer power supply (the positive to the yellow). Will it have an issue down the road? |
