Narrative:

At 9000 MSL lost all electrical power. Turned emergency power on. Left and right aircraft generator showed overvoltage ohms. Frequency reset, showed good voltage plus frequency. Put back on line. Total time maybe 30 seconds. Spent many more mins resetting FMS. Had to use manual pressurization remainder of flight.
