Narrative:
Pulled into gate shut down engines and aircraft went dark. The front and back totally due to the APU not being started. Also no dome light; no VHF #1 and APU would not start! Only battery off light came on #1 battery when both batteries were switched off then on! Alarm went off below in nose wheel well. The only light was IRS on battery light. Ground power was connected in about two to three minutes. The APU started normally and power was normal on the aircraft again. About an hour later the captain called maintenance duty manager and asked for tech support on the airbus 330. They were advised of all of the above. He said would go back to the aircraft and write it up if they thought it needed to be done. He was put on hold and told aircraft had no history of electrical problems; no aircraft alerts or notifications and that a write up was not necessary. He said I am good with it if you are. He just wanted maintenance to know if they thought it was a valid write-up. Maybe batteries never connected back to battery bus? Check electrical switching for faults.
