MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
POWERPLANT WARNING LIGHT ON, DUST DETECTOR WARNING LIGHT ON, BUT
11.
DUST DETECTOR PRESSURE SWITCH(ES) NOT TRIPPED (FIG. 6-2) - Continued.
Disconnect connectors of engine to bulkhead lead assembly 12325929 at engine
Step 4.
disconnect and at bulkhead disconnect. Check lead assembly circuit 509B by
checking continuity to all other connector pins, connector sheels, and groun.
If continuity exists, replace engine to bulkhead lead assembly 12325929
a.
If continuity does not exist, go to step 5.
b.
Disconnect connectors of hull intermediate lead assembly 12325928 at bulkhead
Step 5.
disconnect and at short lead (circuit 509B) from dust detector warning light box
harness connector. Check for lead assembly 12325928 at bulkhead connector by
checking continuity to all other connector pins, connector shells, and ground.
If continuity exists, replace hull intermediate lead assembly 12325928 (para.
a.
b.  If continuity does not exist, go to step 6.
Disconnect connector P1 of dust detector warning light wiring harness from dust
Step 6.
detector warning light box. Check for circuit between dust detector warning
light box and harness assembly by checking for continuity between connector
pins C and B and between connector pin C and connector shell.
a.  If continuity exists, replace dust detector warning light harness (para.
b.  If continuity does not exist, replace dust detector warning light box (para. 6-
17g, M60A3; 6-17h, M728; 6017i, M48A5AVLB, M60A1AVLB).
POWERPLANT WARNING LIGHT NOT ON, DUST DETECTOR WARNING LIGHT NOT ON,
12.
DUST DETECTOR PRESSURE SWITCH(ES) NOT TRIPPED, DUST INGESTION IS
APPARENT.
Service dust detector filter strip (see quarterly PMCS, item 23).
Step 1.
Check air pressure hoses for blockage and correct installation (para. 6-17 b).
Step 2.
Perform dust detector operational test (para. 6-17j).
Step 3.
If dust detector is operational go to step 6.
a.
b.  If dust detector is not operational, go to step 4.
Replace dust detector pressure switch(es) (para. 6-17b).
Step 4.
Perform dust detector operational test (para. 6-17h).
Step 5.
If dust detector is operational go to step 6.
a.
If dust detector is not operational, notify support maintenance.
b.
Step 6.
Change engine oil and filter. Run engine 10 hours. Take engine oil sample and
submit to AOAP laboratory per LO-12.
