TEST OR INSPECTION
While starting generator set,
check voltage on high pressure
fuel pump connector J14-A(+) and J14-B(-).
If voltage is 16-24 Vdc, go to Step 4.
less than 16 Vdc,
check battery voltage.
Replace or recharge battery (paragraph 4-27).
good, replace EECM (paragraph 4-64).
Check for 24 Vdc on transfer pump connector P17-A(+) and
If 16-24Vdc present, go to Step 6.
If no voltage,
disconnect battery cable plug connector.
Visually inspect for damage and check continuity on wires
U117A16 (TB3-19 to P17-A) and V102AF16 (TB3-1 to P17-B).
Replace if damaged, shorted, or no continuity.
Check fuel flow of transfer pump (paragraph 4-37).
If fuel flow is correct, go to Step 6.
If fuel flow is low, service transfer pump (paragraph 4-37)
and connecting fuel lines.
Replace pump if necessary.
Disconnect outlet fuel line from solenoid valve.
outlet line into a suitable container.
Start generator set and
check fuel flow.
If fuel flow good, refer to next higher maintenance level.
If fuel flow appears low,
ensure that solenoid valve fuel
lines are not restricted.
If no restrictions, replace
solenoid valve (paragraph 4-42).
GENERATOR SET SHUTS DOWN WITH LOW OIL PRESS MALFUNCTION LIGHT AFTER READY TO
LOAD BUT STILL IN NO LOAD.
Inspect generator set lubrication system for leaks and damaged
hoses (Section XII).
Tighten loose fittings and replace damaged hoses.
