| Susurrous:
I'm restoring a Mortal Kombat I arcade cabinet and the last bit of wiring left to do are the two 5.9 Vac coin chute lights on the door. The cabinet has a newer Wells-Gardner monitor that doesn't require an isolation transformer. So all I have is a power supply for the MK1 PCB—but no fuse/fuse holder, no line filters, no distribution block, etc. The marquee halogen light now runs to a standard power outlet. So my question is, what's the easiest method of powering these lights when the cabinet is turned on? I have several free plugs inside on a power strip. Or would I just run the wires directly to the power supply? (12V, 5V, -5V?) I wouldn't do this is there was potential to damage or drain power to the PCB(s). |

What kind of light bulbs are currently in place in your coin reject slot? I believe your voltage should be DC, not AC. Sent from my iPhone using Tapatalk |

They're just the standard GE#555 bulbs. |

Being that these bulbs don’t run on AC voltage, tap into the switching power supply to get the DC voltage that you need. I wouldn’t worry about two bulbs drawing too much power and if you are, replace them with LEDs bulbs. Sent from my iPhone using Tapatalk |

You can run ground and 12v lines from the power supply and wire the two bulbs in series like this: 12v--------555 bulb 1----555 bulb 2--------ground Each bulb will drop 6v (half of the 12v) and you'll draw slightly less than 0.25A. Running at the lower voltage will slightly extend the life of the bulb. Stranded wire between 20AWG-24AWG will easily handle that much current and be easy to work with. :cheers: Scott |
