Set main quantity selector switch (3) R MAIN.   Fuel quantity indicator (4) shall read amount shown in Table 8-11.1.  If not, go to task 8-11.10. 7. Set fuel quantity selector switch (3) to R FWD. Fuel quantity indicator (4) shall read amount shown in Table 8-11.1.  If not, go to task 8-11.11. 8. Set fuel quantity selector switch (3) to R AFT. Fuel quantity indicator (4) shall read amount shown in Table 8-11.1.  If not, go to task 8-11.12. 9. Set fuel quantity selector switch (3) to TOTAL. Fuel quantity indicator (4) digital readout shall indicate amount shown in Table 8-11.1.  If not, go to task 8-11.13. 10. If L FUEL LOW (Without  74) L FUEL LVL (With  74) warning capsule (5) on master caution panel (6) is on, go to task 8-11.14. 11. If  R FUEL LOW (Without 74) R FUEL LVL (With  74) warning capsule (7) on master caution panel (6) is on, go to task 8-11.15. 12. To check low fuel warning on left main fuel tank, drain If L FUEL LOW (Without If) L FUEL LVL (With 74) tank until fuel level is below 320 to 420 pounds. warning capsule (5) on master caution panel (6) does not come on, go to task 8-11.16. 13. To check low fuel warning on right main fuel tank, drain If R FUEL LOW (Without 74) R FUEL LVL (With 74) tank until fuel level is below 320 to 420 pounds. warning capsule (7) on master caution panel (6) does not come on, go to task 8-11.17. TASK RESULT CHECK FUEL QUANTITY AT REFUEL  PRECHECK PANEL 14. Check that FUEL REFUEL circuit breaker (8) is dosed. If circuit breaker (8) is open, dose it.  If it opens again, go to task 10-3.5. 15. Set REFUEL STATION switch (9) to ON. 16.    Set PWR switch (10) to ON.   Light (11) shall come on.  If light (11) does not come on, go to task 10-3.8. 17. Turn fuel quantity selector switch (12) to each posi- Fuel quantity indicator (13) shall read amount for each tion.  Record fuel quantity reading on fuel quantity switch position shown in Table 8-11.1.  If indicator does not indicator (13) for each switch position. read any amount for all switch positions, go to task 8-11.18.  If indicator reads amount for all but one position, go to task 8-11.19. 18. Set PWR switch (10) to OFF. 19. Set REFUEL STATION switch (9) to OFF. FOLLOW-ON MAINTENANCE: TM 55-1520-240-23: Battery disconnected. Electrical power off. Hydraulic power off.
