  • Carnetix P2140 starting mac mini

    Hello all

    Today i got around to installing my mac mini car computer with P2140 PSU/controller

    When i tested it with a powersupply a few weeks ago everything was working as it should

    now when i turn on the ignition, the p2140 powers up and starts flashing but it never triggers the mini, i can manually short the pins on the switch cable and it will start no problems

    any ideas why it would not be automatically starting?

    Most likely, you don't have the power supply wired properly. Check your connections.

      Power supply is wired pos to pos, ground to ground and yellow to acc

      connection from power supply is via mac pac prewired cable

        You'll probably want to hook the 2140 up a computer via USB and see what it's doing with the PSUmoni software.

            The 2140 can sometimes get 'scrambled' -especially during testing or if your battery goes dead. Hook it up to the USB and reflash it. That may do the trick.

              It appears it was a broken green acpi wire on the 'quality' mac pac cable

              soldered it back on the plug and that problem is now solved

              Now i have an issue of that it is sleeping my mini fine but then after around 1 minute its cutting power to it

              software is set to sleep mode
