    Did I hook something up wrong? M2-ATX problem

    Well I can't seem to get any power whatsoever from my M2-ATX. I looked around a few of the M2 problem threads but nothing really stuck out to me.

    I've got my mobo, M2, RAM, and HDD in the computer right now. I've got the leads for ground, power, and ignition directly wired to the battery, ground to negative, power and ignition to positive. The M2 has the power button from the case attached to the J9 jumper, and the M2 is wired to the power button jumpers on the mobo (pins 6 and 8 on my M10000) from the J8 jumper. I've tried switching the polarity of the J8 jumper since it's not labeled which pin is + and which is - on the M2 or in the manual. The 'function' jumper on the M2 is set to B which is 5 sec/2 hours as the M2 manual suggests.

    Am I missing something here? Shouldn't I be getting SOMETHING atleast when I touch the power wires to the battery? As it is right now I'm not even getting spinning fans.

    What happens when you short the mobo manually?

    Ok well I tried this:

    I took the jumper off of the power switch pins on the motherboard. The M2 is still plugged in to the motherboard and the hard drive power spots. I hooked power to the M2 from the battery, and then used a small screw driver to touch the two power switch pins on the mobo. Did I do that right? Because when I tried that, I again got nothing. No spinning fans, no beeps, nothing. The jumpers on the M2 are set to "dumb PSU" mode.

    EDIT: I'm no pro with a multimeter, but I did test and the M2 is getting power through the ground, power, and ignition leads. It is NOT, however, making any sort of output through the ATX connector. Does this mean I've got a toasted power supply?

    Yes you shorted it right assuming the jumpers you shorted were the on/off pins. If there is no power through the ATX connector, then something is wrong. Check pin 14. Greenish. That always has power. It is what is actually used to turn on the computer.

    No dice on pin 14. Went ahead and tried all 20 pins and all the molex connectors to the HDD and such. Completely dead.

    Does the MB work with a known good ATX supply?

    The MB has worked fine for me using a standard home ATX power supply. I've been working on setting up my front end, GPS, music, and phone control in the house and I went to install the carputer in the truck once I'd finished and the M2 just decided it didn't want to work for me.
