Troubleshooting Recommendations:

NOTE: It is normal to observe the "R BATT OFF" light on the electrical control panel illuminate momentarily during the APU start sequence. The right battery contactor is opened during this sequence to isolate the right battery from the right essential bus to prevent a voltage drop on the essential busses. During this sequence you will also observe the R BATT flow line white on the electrical synoptic page.
