CORRECTIVE ACTION
Step 13. Disconnect P5 from EECM and check continuity between P5-D and
P12-A, and between P5-E and P12-B.
Replace wires if damaged or no continuity.
If there is continuity, replace EECM (paragraph 4-64).
10. UNIT ATTAINS IGNITION AND RUNS BUT READY TO LOAD LIGHT DOES NOT COME ON.
NO MALFUNCTION LIGHTS.
WARNING
To prevent injury, ensure that
battery is
disconnected before
repairing or
replacing damaged
wires.
Step 1.
Check VOLTAGE meter on control panel for voltage indication of
20-35 Vdc.
If VOLTAGE meter reads zero or very low voltage, go to
Step 2.
If voltage is correct,
shut down generator set.
Press to
test READY TO LOAD light.
If light does not come on,
replace lamp (paragraph 4-74).
If lamp is good, open
control panel and check for 24 Vdc between pins of READY TO
LOAD light (DS1).
If voltage is correct, replace socket
(paragraph 4-73b).
If no voltage, disconnect battery cable
plug connector.
Inspect and check continuity on wires
U122A18 and V102S18N.
Replace if damaged or no continuity.
Step 2.
With unit running, monitor BATTERY CHARGING meter.
If BATTERY CHARGING meter reads less than -5 amps, shut
down generator set and go to Step 3.
If BATTERY CHARGING meter reads more than -5 amps and more
than 20 seconds have passed since attempted start, shut
down generator set.
It may be necessary to disconnect
battery to stop unit.
Inspect starter and solenoid for
damage and to see if starter is engaged. Replace starter
if necessary (paragraph 4-32b).
