2.) Operate the unit through the appropriate modes to see if any active alarm
occurs. Continue with the steps below as necessary.
1
Check For Alarm 130 - Check RPM Sensor
Check for alarm 130.
When Alarms 130 and 41 occur at the same time,
generally the engine has run out or is running out of
fuel. This causes the engine RPM to surge and drop.
Check fuel tank and add fuel as necessary.
Check fuel lines between the fuel tank and the fuel
pump inlet for drawing air in.
2
Check For Flash Code On Engine Speed Control Unit (ENSCU)
Check for flash codes on the ENSCU. Refer to ENSCU LED Fault Chart, Section 9.5, must
be no LED alarm codes occurring to continue.
3
Was Engine Shut Off Manually?
Check for external cause.
Correct problem.
4
Check For Bad F2 Or F3 Fuse Alarm
Check for alarm 71.
Alarm conditions must be corrected and the alarm
cleared to continue.
5
Check Fuel System
a. Check for Alarm 1.
Fill tank as needed.
b. Check fuel flow.
Unrestricted fuel flow through system.
Fuel not gelled.
c. Check fuel system prime.
No air in fuel system.
d. Check fuel system check valve
from filter to injection pump.
Check valve must hold fuel and not leak back.
6
Check Fuel/Speed Actuator (FSA)
a. Check Run Relay LED.
LED 28 must be ON.
b. Check voltage to ENSCU.
Use Component Test Mode to energize Run Relay.
(Refer to Section 5.2.2.)
Must have 12.0 VDC or higher reading between
ENSCU 13 and 19.
c. Inspect ENSCU connector pins &
terminals.
No damage, moisture, or corrosion in connector.
d. Inspect harness & control box
connector pins & terminals. (See
wiring schematic Section 10.)
No physical damage to harness.
No damage, moisture, or corrosion in connectors.
e. Check resistance of FSA.
Refer to Section 2.12 for correct electrical values.
f.
Check operation of FSA.
Plunger must move in when energized.
g. Check connections at splice
points SP3, SP5 ans SP6.
Connections must be good condition. No loose or
broken wires.
