General Maintenance Action
Aircraft; Manuals
Just short of the gate [the First Officer] engaged the APU (Auxiliary Power Unit) starter. This action caused a DC bus fault; a Number 2 Generator fault and the APU appeared electrically dead. We stopped the aircraft; set the [parking brake] and pulled the Non-Normal Checklist. Next we called Maintenance and we were instructed to try to start the Number 1 Engine. The engine spooled up slowly and weaker than normal so I discontinued the start before the introduction of fuel. The main battery started to rise in temperature very quickly. So we powered the aircraft down; removed the passengers and notified Maintenance.
The pilots of a commercial aircraft were unable to start the Auxiliary Power Unit due to an unknown electrical problem. Maintenance suggested restarting the left engine; but the attempt created a rapid rise in the temperature of the main battery; so the Captain aborted the start and powered down the aircraft.
