Help with power supply

Archived from groups: alt.games.mame (More info?)

I should probably start by saying, I am not electrical savy. With that
said, keep it simple for me k?

I purchased a Tekken3 arcade game, which originally housed a Street
Fighter2 Championship Edition PCB. I purchased this box with the
intent to gut it out so that I could build a mame system.

I'm using a PC with an Ipac keyboard encoder. I took out the jamma
board as I decided to not build my system around jamma. After taking
out the Jamma board the power supply now doesn't turn on. Unfortuntely,
I tossed the board so now I can't get it back to troubleshoot through
the process of elimination.

My only use for the power supply is so that I can power on the arcade
monitor. I should also add there is a transformer connecting to the
power supply.

Any ideas would be appreciated. thx.

    A pic?. no i dont have a camera. nothings left of the jamma board. i
    tossed it compleltey, but kept the jamma cables.

    I think i know whats wrong though. i believe its because the power
    supply is "switched" and since theres no pcb board trying to draw power
    its failing to start. stupid me. i knew of this concept but didnt think
    about it.

    anyone with any ways to get past a switched power supply?

    I know the JPAC doesn't use any power and you can use it without a power
    supply. The reason I asked about a picture is did you remove the Isolation
    transformer? If so this is what you need to power your arcade monitor.

    My monitor is connected to a transformer before the power supply. maybe
    this is why there is no draw?

    thanks for your responses everyone.

    If your monitor uses and isolation transformer you might be tempted to
    bypass it. RESIST THE TEMPTATION. It is a CRITICAL safety feature.

    Typically the monitor power comes from the power supply on a couple
    separate 110v connections. Your power supply probably has two 110v, a
    +12v, +5v, -5v, and maybe a -12v and a couple ground connections. When
    it is plugged in it will draw little or no power unless there is a
    demand for it, same as a power strip. If your monitor is connected
    correctly I assure you it will come on.

    What is your transformer connected to? You might post in
    rec.games.video.arcade.collecting to see if someone can scan you part of
    the manual that shows the proper way to wire up your game. Of course
    you are only concerned with the monitor part, but there is probably a
    diagram in the Tekken3 manual.

    The transformer has how many leads? The green one is ground, and
    usually fused if IIRC (consult manual or an electrician) and the black
    or white are your 110v.

    Good luck.
