 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.
