CORRECTIVE ACTION
3. ENGINE SHUTS DOWN SOON AFTER STARTING-continued
Step 7.
Remove temporary short from oil pressure switch OP1 and use multimeter to check for presence of 24V
DC across fuel level switch FL4 (see figures 4-33 and 4-34).
If 24V DC is present, test the fuel level switch, and replace switch if defective (see paragraph 4-
55).
If 24V DC is absent, low fuel shutdown relay K8 may be defective and must be referred to higher
maintenance.
Step 8.
Check oil pressure gauges (see figure 4-40).
If INPUT gauge reading is normal and OUTPUT gauge reads low, check and service spin-on oil
filter (see paragraph 4-8 c (2).
If INPUT gauge read low and OUTPUT gauge reads normal, check lube oil lines for damage or
blockage. Replace defective hoses and fittings.
If both gauges are normal, refer to next higher level of maintenance.
4. ENGINE SHUTS DOWN AND WILL NOT RESTART.
Step 1.
If HI COOL TEMP indicator lamp is lit, and coolant level is normal, test thermostats (paragraph 4-80).
Replace thermostats if defective.
If high coolant temperature condition persists, refer to next step.
Step 2.
Refer to paragraph 4-49 on radiator assembly maintenance and check fan belt tension, Code A only. No
fan belt on Code B.
Adjust or replace belts as necessary, Code A.
If high coolant temperature condition persists, refer to next step.
Step 3.
If HI LUBE TEMP indicator lamp is lit, and lube oil level is normal, check INPUT and OUTPUT OIL
PRESSURE GAUGES (figure 4-40).
If INPUT GAUGE reading is normal, and OUTPUT GAUGE is low, or if INPUT GAUGE reading is
low and OUTPUT GAUGE is normal, refer to Malfunction 3, Step 8.
If both gauges are normal, refer to next higher level of maintenance.
