| Kevin Mullins:
Before going into the pc power supply part of it.... lets clarify the isolation transformer for the monitor. (that's very important as already mentioned) Can you take a pic or mark on one you already have as to what YOU are calling the isolation transformer? Because the part you have marked as AMP I believe is actually the isolation transformer you need. The purple and white wires appear to go from the "amp" straight up to the monitor. |

Hey, Thank you for posting Kevin, I appreciate it. Yea, I am probably wrong. (Pictures below) In the first picture, the yellow arrow line points to what I thought was an amp of some kind for the monitor, but, as you said, it is probably the isolated transformer (That would make sense, because it is isolated. Misconception on my part, sorry.). The red line points to what I thought was the isolated transformer. So basically, I thought the piece underneath the monitor was the isolated transformer. If it is as you say, and what I thought was the amp is actually the isolated transformer then yes, the purple and white wires go straight from the isolated transformer and to the monitor as you pointed out. New diagram below. Thank you for correcting me on that. (I feel stupid.) : |

Everybody has to start somewhere, don't sweat it! At least you're asking questions first instead of just plugging things in without a clue what you're doing! What you are currently calling the "amp" at the bottom of the cab is indeed the isolation transformer. The part you label in red as the transformer is the monitor chassis. |

Hey, Thanks for the encouragement paladin. So, from the pictures I posted earlier, can anybody tell me if I have a different power setup than the one Krick suggested? It looks like it to me, but I could be missing something. Either way, I still need a method to power my pc and monitor in my cabinet. I am open to any kind of help possible. I am in no rush, and haven't bought anything yet (except the cabinet of course). For those who don't want to read all the previous posts, this is my problem: I recently bought a working Tekken 2 arcade cabinet and want to convert it to Mame. I decided that to do this I would buy J-Pac, and Arcade VGA and use them in conjunction with my pc (Seeing that it seems to be the easiest way to do it). But RayB informed me that I shouldn't use the arcade power supply and a pc power supply together. So, I need some way to power my pc and the monitor. Krick posted an AC wiring diagram, but I believe mine is different from his. As Krick mentioned, in his diagram, you could completely remove the power supply and the monitor and marquee would still receive power. But in mine, the AC in seems to go straight from the wall to the power supply. Thus the power supply seems to be functioning as the main hub for all power. From the power supply, wires split off into these three directions: (1). To the Jamma Harness. (2). To the Isolation Transformer, then to the monitor. (3). To the on/off switch and marquee. In each direction there is Molex that would allow me to disconnect any section I want. (I corrected my power diagram and it is in post number 6. It vaguely outlines where my power is going.) Thanks, once again. |

OK this is a tricky one. I am experienced with pre-90's cabinets. Yours is different than the standard "jamma" set up. You seem to have a "special" power supply that takes care of ALL power (AC and DC). This is unusual. I'll step out of advising here and let someone who's seen one of those help you out... PS: You should let us know if you intend to keep the machine capable of playing JAMMA games, or if you will be strictly using MAME? |
