FUEL SHUTDOWN SOLENOID TEST (continued)
FIGURE F.3 – FUEL SHUTDOWN SOLENOID LOCATION
TEST PROCEDURE
1. Turn the engine off.
2. Open the right side engine service access
door.
3. Locate the fuel solenoid, located on top of
the engine.
4. Locate and unplug harness connection P/J
73. Cut any necessary cable ties. See
Figure F.4. See Wiring Diagram.
5. Using the Ohmmeter, check the pull-in coil
resistance, (black wire to white wire). The
normal resistance is less than 0.5 ohms.
Check the hold-in coil resistance, (black
wire to red wire). The normal resistance is
approximately 11 ohms. Check the
Resistance between the black wire and a
clean, unpainted chassis ground. The
resistance should be very high, 500,000
Ohms or more. If any of the above resis-
tance values are incorrect, the solenoid
may be faulty. Replace.
6. Using an external 12VDC supply, apply
voltage to the pull-in coil leads, (black-) to
(white+). The solenoid should activate.
REMOVE THE VOLTAGE immediately to
avoid damaging the solenoid.
Apply 12VDC to the hold coil, leads,
(black-) to (red+) While the voltage is
applied, manually move the solenoid to
the fuel on position. The solenoid plunger
should hold this position until the voltage
is removed.
If either coil does not operate as
described, check for mechanical restric-
tions or other problems with the linkage.
If the linkage is intact and the solenoid
does not operate correctly when 12VDC
is applied, the solenoid may be defective.
Replace.
Re-connect fuel solenoid and replace any
previously removed cable ties.
7. If finished testing, close the engine ser-
vice access doors.
