You have a 120v fault that is blowing that fuse, so the only thing left is that cord. It is not likely to be where the cord connects to the circuit board IMO. It is more likely to be farther out near the end where it was cut and since then it got wet out there. Perhaps now cut it way back shorter, and splice on the new bit of cord with a plug on it and try again.
The fuse is after the cord; a short in the cord would not cause the fuse to blow because the short circuit current doesn't flow through the fuse, and likewise an open or high resistance in the cord would not cause the fuse to blow because it only could reduce the current that's flowing.
