For this to be an electrical resistance caused fire, I would first have to believe that some Boeing engineer was so incompetent that he was unable to read a very basic chart that defines the wire/cable size required to handle x current (amps) over y distance (feet). Additionally, if the aircraft were powered down, how much current would be flowing through these circuits? Are there circuits in the area of the burn (e.g. ELT) that are left live and do they carry enough of a load to generate the resistance/heat to trigger combustion? Once again, I would find it incredibly unlikely that the cables wouldn't be sized for the current loads.
