| question about grounds for my lights for my coin doors |
| (1/1) |

So tonite I got my coin doors to work - i drop in a quarter, system registers. Fine and dandy. Anyways, on the one coin door, each light has its own separate power wire and ground wire. However on the other door it has just a single power wire that feeds both lights, and a single ground cable. Now this ground cable is also the ground for the switches, or common i should say. Would it hurt anything if I ran said wire as a ground, or should i just rewire the lights? |

Is this in a mame machine running a PC or an original cab? If it's a mame/pc setup, I would separate the bulb ground from the coin switch ground. The bulbs will run with a 12v dc power source and the ground from this power source will need to be isolated from the switch circuit. Not a good idea to send any stray voltages to your Ipac or Keywiz. |

If the 12V is coming from your computer power supply you should be fine. If this is a separate power supply, it could affect more than just the keywiz/ipac. The safest bet is to isolate the 12V ground from the 5V ground though. |

Good call. I'm just going to re-wire the lights and have a separate ground. Thanks gents. |
