1. Interrogate the MDC as follows:

   1. On the cursor control panel, ensure the toggle switch is to the right and select Anti-Ice, ECS and Fuel buttons simultaneously. The MDC main menu should now be displayed on Display Unit #3.
   2. Using the joystick, select Current Faults (if the fault is active) or Aircraft History to research stored faults. From Aircraft History you can then select Fault Message History and locate the fault.
   3. Check advanced diagnostics for the generator fault, select the MDC equation or nomenclature from the drop down below to provide additional information to assist in troubleshooting.
      Select an MDC Fault Code/Message:B3-006657 - DPMS2/RPROT/WIRING FAULT [DIFF PROT SNSR 2]B3-007019 - FAULT [L BUS TIE CNTOR]B3-007688 - FAULT [R BUS TIE CNTOR]B3-007766 - FAULT [R GEN GCU]B3-007767 - INTERNAL FAULT [RIGHT GENERATOR]B3-007768 - FAULT [R GEN LINE CNTOR]B3-007769 - FAULT [R GEN PWR MODULE]B3-269321 - SHORT CIRCUIT [BUS TIE FEEDER]
      

NOTE: In the event that no MDC faults are posted, please note that the DC Generator, the Generator Line Contactor (GLC) and the Generator Control Unit can be swapped for troubleshooting purposes.
