APU滑油量低或者启动发动机的二极管短路
MAINT Light
The ECU uses the MAINT light to tell you when the startergenerator
has a shorted rotating diode. Repair the startergenerator
as soon as possible.
The ECU also uses the MAINT light to tell you the APU oil level
is at low oil quantity (LOQ). When the oil level is at LOQ, there is
enough oil in the APU for 30 - 50 hours of operation at the
maximum oil consumption rate before the APU will shutdown
because of low oil pressure. However, if there is an oil leak, the
APU will not operate the 30 - 50 hours before a low oil pressure
shutdown occurs. Add oil to the APU as soon as possible.
You can also use the ECU to deactivate the MAINT light
because of incorrect low oil quantity (LOQ) indication. It is
possible to deactivate the MAINT light if the MAINT light comes
on when the quantity of oil in the APU gearbox is satisfactory
during an airplane landing operation. Boeing Service Letter
737-SL-49-058 gives more data on the deactivation of the MAINT
light and low oil quantity indication.

起动机的二极管短路，只是维护灯亮，对APU启动没什么影响吗
