If the APU should shut itself down, or does not start for any reason
Place the APU CONTR switch OFF Do not cycle the BATT switch with the APU CONTR switch ON as this may cause the APU to restart (possibly resulting in overspeed/overtemp of the APU) Turning the BATT switch OFF or cycling the APU CONTR switch will reset ESU and malfunction BITE indicators, resulting in loss of shutdown reason.
