3. Fault Confirmation
__________________
A. Test.
(1) Do a test of the vacuum toilet system (Ref. AMM TASK 38-31-00-710-009).
B. Do the bite test (Ref. AMM TASK 38-31-00-740-001).

4. Fault Isolation
_______________
A. If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
B. If the operational test is not satisfactory:
- Refer to the trouble shooting page of the bite test.
(Ref. Fig. 201/TASK 38-31-00-991-001)
(1) If the TROUBLE SHOOTING DATA page gives the maintenance message VACU GEN SUPPLY: - open and close the circuit breaker 35MG (Ref. TASK 24-00-00-810-
818).
(2) If the fault continues:
(a) Do a check to make sure that the motor start relay 36MG functions correctly when energized:
- make sure that the voltage at the contactor 36MG-A of the motor start relay is correct (Ref. ASM 38-31/10).
- make sure that the circuit breakers 32MG, 33MG, 34MG are open.
- with the circuit breakers 33MG open and 35MG closed do a continuity check between terminals L1-T1, L2-T2 and L3-T3 on the motor start relay 36MG (Ref. ASM 38-31/10).
(b) Do a check to make sure that the motor start relay 36MG functions correctly when de-energized:
- make sure that the circuit breakers 32MG, 33MG, 34MG and 35MG are open.
- make sure that there is no voltage at the contactor 36MG-A of the motor, do a continuity check between terminals L1-T1, L2-T2 and L3-T3 on the motor start relay 36MG (Ref. ASM 38-31/10).
(3) If there is no continuity in step (2) (a), or continuity in step (2) (b):
- replace the RELAY-MOTOR START (36MG), (Ref. AMM TASK 38-31-36-000-001) and (Ref. AMM TASK 38-31-36-400-001).
(4) If the fault continues:
- do a check of the fan phase relay (Ref. ASM 38-31/10), if necessary:
- replace the RELAY-FAN PHASE OFF (38MG), (Ref. ESPM 204650).
(5) If the fault continues:
- replace the GENERATOR-VACUUM (37MG), (Ref. AMM TASK 38-31-64-000-001) and (Ref. AMM TASK 38-31-64-400-001).

C. Test
(1) Do the test as given in paragraph 3. A. to check the correct operation.
(2) After the subsequent flight, make sure that the fault does not continue.
