Lets see... battery wires hot, means the current is flowing through there too much so the fault is after it. CIMs cold, means the fault is prior to the CIMs. I also assume that you're robot didn't give you a massive shock as if it had a short to the frame. (540's machine did this in our last elim match) The red light is blinking, but the breakers aren't tripping. The RC is good and the Victors still work (can't be a short there, you'd likely damage the Victor if it was on input, or you'd pop the breaker if it was in output. This leads me to think you have a internal fault in your IFI breaker panel. (further evidenced by trannys that worked in a robot with identical power distro failing here) As to the temporary improvment, maybe the replacemnt moved something around that fixed it for a short time. (At VCU our pwm02 was ignoring input and constantly giving reverse values, a little messing with the cable, and it worked. Then after a match it messed up again, only fixed by changing the fuction over to pwm03. The moral? Don't assume the IFI part works perfectly, IFI makes quality components, but has manufacturing faults just like everyone else, especially when their parts are used in a rough, competitive environment, being handled by high school students who are running on very little sleep) As to the loss in RPM, I haven't a clue.
