    P1900 problems

    I have gotten all my wires run, and when I start the car, the P1900 red LED blinks once and I get no fan action at all. Anybody seen this? I tested the hot wire to the battery and its getting >14v, and the resistance on the output socket looks good. If I test the output wires I get no current at all...

    Does the grn/blk ACPI wire have to be hooked up to the pc for it to function correctly? I haven't done that yet, I'm just trying to get some juice flowing through the unit.

    Does the IGN wire of the P1900 have to be connected for the unit to work, or does that just control the SSC aspect of the unit?

    I don't have this setup, but I can guess.

    If you do not have it on Dumb PSU mode (if that model even has it), then it won't know when to activate the rails. So no power. If it receives the ign, then it thinks, "hey lets start up", and starts pulling power off the 12v constant.

    Basically for testing, connect the ign wire. Put it in Dumb PSU mode if there is one, otherwise.

    I know that is how the M2-ATX works..

    Yes, it's a must.

    you can join the ACC and the Constant 12v and it should start there. I have the P1900 and havent had too many problems with it.
    When the ACPI wires get shorted that sends power to the output cables to start the Mobo
