  • Newbie with Auto-Power Issue =(

    Hey guys,

    I've been doing this carputer for my first time and I can get the computer working by pushing the on button and screen working fine however I can't get the computer to auto turn on with the ignition...

    From what I gather:
    Black wire to black on battery,
    red wire to ground on car,
    grey wire to an ignition but it's just not happening for me =(

    Could anyone shed some light on this issue for me please?

    Thanks

          speedyvr6 is correct.

          the black wire goes to ground, and the red wire goes to the +12v terminal on the battery. just be sure to fuse the wire within 18" of the battery(i prefer less then 12", but iasca spec is 18"...)

          and yes, the white wire would typically go to a switched source, like a ignition line. the alternative is to connect a switch off the red wire to control weather the white wire recieves power. this would perform the exact same function, but would not automatically turn the pc on/off.

            Thanks guys, makes sense. Am sat in my car now and still not having much luck with this.
            Power is getting to the carputer. Red is now red with battery, black is grounded and white just seems to be doing nothing to autostart the computer, no matter where I stick it (no funny comments please :P) there seems to be no signs of an autostartup!

              Okkkkk, got it to bootup on ignition by changing the BIOS yeay!!!
              Issue I now have is that when I switch the car off the computer has hard shut off instead of shutting down nicely. Anyone with more idea why than me? Any help is appreciated, thanks

                What FE are you using?

                In CF, there is a setting in the menus to adjust what action you want the PC to take when power is cut.

                  rubber chicken, see if your jumper is set to "A" on your M2-ATX which gives you a five second delay for startup/shutdown.

                  Good Luck.

                    Having problems loading Cf which is a different issue altogether

                    Also I'm gonna sound numb but jumper set to A? I'm a noob doesnt mean much to me sorry!
                    I 'think' a jumper are those double prongy things on the boards? And how do I set it to A?

                    Thanks...and sorry

                    Having troubles again with ignition booting too! Arghhhh

                      I am not running an M2 but I'm sure he must be referring to a jumper inside the PS. I know I had to adjust several of them on my PS to get it to behave.
                      I would recommend you go through the manual for the PS, there may be other things you need to change to get it to work properly.

                        It also means that you probably haven't read the manual for your M2.
                        Have you looked in the FAQ yet?
                        How about the Wiki?

                          Ok so I've gone back to the manual and beginning to learn abit finally cheers! it's under J10 and can spot A on the ATX but as I know nothing on electrics I didn't know to switch it on and after googling amd finding very little I asked a friend who advised just to use a white jumper block? This right?

                            The color of the jumpers really doesn't matter, but yes.
