There are no "High voltage" wires in the 747-100. The highest voltage used is 115 volts.

115 volt wires are high voltage compared to the FQIS wires and that's the voltage used in the short circuit tests. It's also 400hz instead of 60hz.

There can be no "short circuit" because signal carrying wires are not going to run through the same conduits as are power carrying circuits.

The only thing I can tell you is that you're wrong. There's a high density of wiring on an aircraft and many of them converge near and in the cockpit. The NTSB found that not only are low and high voltage wires routed together by design, but sometimes they are routed together against design. I do believe they have made recommendations to have the wires separated as much as possible since the TWA800 findings. They've also looked into transient suppression devices to make the wiring safer.

Both sets of wires have insulation on them that are rated for better than 600 volts. That's 1200 volts of insulating capacity between them according to the specs. The 400 hz is immaterial.

No, you cannot "tell" me that, you can assert it, but to "tell" me something, you have to know something about the subject, and I can clearly see that you don't.

And you never did answer my question about what the NTSB would do if the President ordered them to Deem it an accident.

What would they do?
