    I'm tellin' ya man, check your coil ground. I really don't think it will work that way. C'mon, PROVE ME WRONG.

    Edit:
    Haha, just noticed this:

    Try hooking it to a normal ground.

    Ok...I must be thick....if you just left the on/off switch on the inverter alone wouldn't it already function this way? I mean on is on...why do you need to add a relay to make it do as it already does....

    sorry if I am being thick about this....but it just seems pointless to me. Just use the switch that is there.....I mean you could just leave it in the on position and then the inverter would always turn on when the other relay provides power?

    Actually it would be proving you right. I'm soldering a longer ground wire right now to ground to the chassis. This relay will be done, and if some people can't comprehend what i'm trying to do, then they need to quit talking so much and listen more.

    UPDATE:
    Changing my relay's ground to the chassis allowed the Inverter to boot up when turning on the Ignition. Sooooo...........success!...............almost.

    However, when I plugged the pc in, the red overload light comes on and the PC turns off after attempting to boot.

    So I'm thinking my problem now could be as follows:
    When I originally hooked up the relay's ground coil to the AC third prong (ground) plug, I heard several beeps, and then my inverter shutoff completely. Fuses were still intact but maybe I smoked something in the inverter or otherwise messed it up.
    I could test this by re-checking all of my contact points for a solid connection or completely removing the relay and seeing if the 400 watt inverter can boot the computer under default specs (I'd like to try this last).

    If anyone has input before I do this, feel free.

    I haven't read this entire thread but for a good shutdown control of an inverter i use this diagram:



    and the little software prog in this thread:

    New shutdown controller - software

    and here is another thread with more info:

    Ghetto Startup/Shutdown Control for Inverter

    instead of wireing the relay directly to battery power cord of inverter, i used the switch (easier, less power demands, and works perfect), but it does require opening the inverter (really not hard). The only thing bad about the setup is that the inverter shuts off ONLY AFTER the computer shuts down, so if you have a pos that hangs, your inverter could potentially be left off (but it should be stable when only useing solid software like carputer stuff).

    Sweet. When you say test under default specs, what are you talkin' about?

    It's easier with a cube timer hooked to the relay and power switch header instead of trying to hook a relay to the com port and using some crazy software.

    I'd like to see for sure man, cause actually cube timers are expensive...
