Merged in a new electrical system to the dev branch - all the relays / switching are now done to spec from the maintenance manuals and the operations, including of the static inverter, emergency generator, etc should all be correct. Please let me know if you think you find any bugs! And I fixed the displays which sometimes would start self-testing after power transients or electrical failures. Now it will only self test once power is lost for > 3 seconds as per the maintenance manual.
In addition I also allowed the SD pages to be displayed on the E/WD display by holding the SD page button. That doesn't yet work perfectly but its a WIP.
