  • Carnetix 1260 driving me nuts

    I've installed the system in the car:

    Positive direct to the battery
    Negative to ground on the radio harness
    Ign On to the Radio Harness Ign On

    The Carnetix is connected directly to the motherboard using the power cable supplied and the carnetix is connected to the Power Button on the motherboard.

    Wierd things are happening, if I start the car with the ACPI connected to the power buttons jumpers on the motherboard the system powers up for about 4 seconds then switches off. If I power on by shorting the pins on the motherboard it powers up and stays powered.

    Any ideas?? Battery seems fine so can't see it being a power issue.

    It sounds like it might be a grounding issue. Have you tried to ground the carnetix and the motherboard to chassis ground and not to the ground of the radio harness?

      Will give it a go, how come it works fine if I use a case power button on the power jumpers rather than the Carnetix power green/black cable??

        That's a good question, It might have to do with the way you have the P1260 grounded. I had issue with my Xenarc PC and I had to install a small relay to get the P1260 to work because there was no ACPI header and I could just connect the P1260 dierctly to the switch to get it to work.

        If that doesn't work you might want to post on the Carnetix Forum. Mike is really good about answering questions in a timely fasion.

          UK_MP3Car,

          Sounds like you may have your ACPI jumper reversed. It is polarized. The Green wire must go to the +side of the power switch. Try reversing it.

          Here's what the M10000 mobo header looks like.

            Hmmm, already checked that, was the first thing I checked, could it be a grounding issue??

              Hard to tell at this point. Let me make sure I understand you connections:
              Positive direct to the battery
              Negative to ground on the radio harness
              Ign On to the Radio Harness Ign On
              Just to verify:
              So, you have the "Positive" RED battery P1260 input wire on J1 connected directly to your battery...(you need to put a fuse on this line).
              And you have the Black GND wire on J1 connected to the Ground wire in your radio harness? If so, this is not a good idea. You should run this black wire either directly to your chassis or back to the negative terminal on your battery. Use a wire size equivalent to whatever you have run for your Positive inut wire.
              And, the YELLOW P1260 Ignition input is connected to the Ignition line in your Radio harness. This should be OK, unless it's doing something funny.
              The Carnetix is connected directly to the motherboard using the power cable supplied
              This confuses me. If you are using an EPIA 800 mobo (per your sig) you need a DC-DC ATX PSU between the P1260 and your mobo. Do you have something like a Morex 60W PSU connected between the P1260 and your mobo? What case do you have?
              system powers up for about 4 seconds then switches off
              Do you mean the system abruptly shuts down with no shutdown delay from the P1260? Or does the system go into the normal shutdown delay sequence and gracefully shut down after 30 seconds?

              Are you sure you have the RED wire connected to your battery and the YELLOW wire connected to the Ignition? Could they be reversed?

                Hi Mike,

                The Carnetix goes to a Morex Dc-Dc power supply, I have one of the early Mini-ITX cases, but can't for the life of me remember it make/model.


                I'll reroute the ground direct to the battery to see if this helps.

                The system shuts down abruptly after approx 4 seconds, even with ignition on.

                The Red cable goes to Positive 12V and the Yellow goes to the ignition sense cable - I ahev double checked these.

                I'll take out later and refit all the cables, will also check the jumper settings.

                      I never heard back. I'm assuming it got fixed.

                        That said, I can say that the Carnetix Supply is the most robust power supply that I've seen, to date; and the support is better than proficient.

                        If I didn't know better, I would have assumed the Carnetix designers went to Florida State (or maybe MIT).

                              Its was my ACPI connection I think not working properly, all seems fine now after I pulled the supply and resoldered.
