    I agree that the PSU is not blowing the fuse, obviously I am shorting or it is grounding out like some above have said. The question remains what is different when I crank the starter vs. just switching to the acc setting with the key. If the system has a short, it should always blow a fuse and as far as I know there is no contact between the computer system and the ignition wire to the starter. I was asking if anyone knew what is changing to cause the short when I crank the starter.

    My setup is simply a wire directly from the battery running directly to the carnetix(with fuseholder in-line), I have looked at every inch of the wire between those two points, there is no obvious place where it could be shorting out, perhaps it is shorting somewhere in my computer but again, why would it only happen specifically when I crank the engine.

    No ground wire? How about remote/acc?

    Yeah, please tell us where you ground wire and acc wires are connected to and from.

    I don't know much about the carnetix PSU, but if it has a remote/acc wire, then try disconnecting that, and just hook it up to the +9v on a 9v battery, and hook the 9v battery ground to the PSU ground. That way you should be able to tell if it is the acc wire from your ignition or head unit that is causing the short.
