    Sorry to resurrect this, but I think it’s worthwhile. I just wired in a power supply using the above instructions (thanks!). Measures 13v DC at my available plug. But I’m hoping to use it for my colordmd which seems to be taxing the system. I notice the colordmd plug has three wires where my supply only has two outputs. Is one a ground? How do I wire it to power the lcd?

    Thanks

    Quoted from lyonsden:

    Glad this thread helped. If that is a plug to the standard AUX power port on STERN games, then the three wires are GND, +5V, and +12V. GND is at the point side of the plug. Different power supplies supply different voltages and currents. Did the one you get provide both +5V and +12V?

    Yes, that is the six plug Y-connector that came with the colordmd. I thought it runs on 12v based on what i read. Which is which on the other two wires?

    No, the ps I have has only 12v as far as I can tell.

    And thanks for the thread and the response! I’m a bit of an electrical newb.

    Quoted from lyonsden:

    I’m pretty sure you need a power supple with both 5V and 12V like amazon.com link »
    The 5V is what is used to power the display.

    Purchased.
