| Electric shock in my Mame system |

Okay... This is a strange one. Installed a new monitor (its a PC monitor so it has the regular power). If i touch any metal part in the cab (USB connector, VGA Connector, Power Supply metal case, etc), I get an electric shock. I have not measured it, but its enough to wake you up (not hurt you). I get this even if the Powerbar is turned off. I believe it is coming from the Monitor. It is my assumption that something is not grounded properly. Any ideas? I would hate for one of my kids to get zapped. :'( Thanks, B |

probably a half mains shock,all your metal parts are earthed? |

I thought so, but I guess not. how would I do that properly? --- Quote from: grantspain on August 10, 2008, 08:44:36 am ---probably a half mains shock,all your metal parts are earthed? --- End quote --- |

every exposed metal area(coin door,control panel) should all be linked to earth,as should the monitor frame basically all you need to do is connect a wire to each metal part and have a common earthing point where they all connect to which is in turn linked to the earth of the power cable |

I will try that. The monitor has a normal 3-prong computer power cable (since its just a de-cased monitor), so it is not connected, but I assume it is via the cable. B |
