SRT8CUDA Build
When I was installing the battery disconnect switch (on the negative side of the battery), I hadn't bothered to disconnect all the FAST XFI/XIM wiring at the battery. (All the XFI and XIM positive and negative leads must be connected directly to the battery according to the FAST instructions)
During this rewiring and testing of the switch, I inadvertently set up a ground path through the XFI box.
Then when I later fired up the engine, my IAC would not work. After more phone calls to David Page at FAST, he concluded there was something wrong with my XFI box or the IAC.
They have both been shipped to FAST and I just got the results. The good news is my IAC is fine, the bad news is my XFI box has been damaged and needs repair:banghead:
All due to my own stupidity:banghead::banghead::banghead:
