Is the Boeing 787's electrical system working?

After my post yesterday, which quoted an unnamed source who estimates that fixing the Boeing 787's problems could take two years, another insider approached me with details of problems with the 787's electrical system (ES). This source, also anonymous, says he worked as a software engineer at Boeing for a decade and is close to the 787 program.

This source claims that the 787's ES failed Federal Aviation Administration (FAA) inspection last year so the FAA ordered the firm responsible for the ES's software to rewrite the code. In my reporting yesterday on potential delays, Boeing spokespeople denied knowledge of any serious problems with the 787's systems.

As claims of problems increase, in my mind, this raises some serious questions about Boeing's board.
