SHUTDOWN SOLENOID TEST PROCEDURE

TEST PROCEDURE

1. Turn the engine off.

2. Unlatch, lift, and secure the right side engine ser-

vice access door.

3. Locate and separate J54 / P54 connector that

attaches the shutdown solenoid leads to the wiring
harness leads ( #262, #232 and #265). See Figure
F.5 and the Wiring Diagram. Remove any neces-
sary wire wraps.

4. Check the pull-in coil resistance (Black to White

#232 to #265). The normal resistance is approxi-
mately 0.2 ohms.

Check the hold-in coil resistance (Black to Red
#232 to #262). Normal coil resistance is approxi-
mately 11 ohms.

If either coil resistance is not correct, the solenoid
may be faulty. Replace.

5. Using the external 12VDC supply, apply 12VDC to

the pull coil shutdown solenoid terminals (#232M+
to #265-). The solenoid should activate.

When the solenoid activates, remove the voltage sup-
ply immediately. Leaving the external supply con-
nected to terminals #232M and #265 for longer than
three seconds will damage the coil.

• The solenoid should deactivate when the 12VDC is

removed.

If the solenoid does not operate properly, check for a
mechanical restriction in the linkage.

7. Using the external 12VDC supply, apply 12VDC to the

hold coil solenoid terminals for the hold-in coil (#262-
to #232+). Push in the solenoid plunger. With 12
VDC applied to the hold-in coil, the plunger should
stay in until the 12 VDC is removed.

8. If the linkage is intact and the solenoid does not oper-

ate correctly when the 12VDC is applied, the solenoid
may be faulty. Replace.

9. Replace harness connector. See Figure F.5 and the

Wiring Diagram. Replace any previously removed
wire wraps.

10. Close and secure the right side engine service access

door.
