TEST PROCEDURE

1.Turn the engine off.

2.Unlatch, lift, and secure the right side engine service access door.

3.Locate and remove the four spade connec- tors that attach the shutdown solenoid leads to the wiring harness leads (#224, #262, #232M and #265). See Figure F.6 and the Wiring Diagram. Remove any necessary wire wraps.

4.Check the pull-in coil resistance (larger ter- minals #232M to #265). The normal resis- tance is approximately 0.4 ohms.

Check the hold-in coil resistance (smaller terminals #224 to #262). Normal coil resis- tance is approximately 20 ohms.

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

5.Using the external 12VDC supply, apply 12VDC to the larger shutdown solenoid ter- minals (#232M+ to #265-). The solenoid should activate.

CAUTION

When the solenoid activates, remove the voltage supply immediately. Do not leave the external supply connected to terminals #232M and #265 for longer than three seconds. Component dam- age could result.

The solenoid should deactivate when the 12VDC is removed.

6.If the solenoid does not operate properly, check for a mechanical restriction in the link- age.

7.Using the external 12VDC supply, apply 12VDC to the smaller idler solenoid terminals for the hold-in coil (#262- to #224+). 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 operate correctly when the 12VDC is applied, the solenoid may be faulty. Replace.

9.Replace harness leads to the correct termi- nals. See Figure F.6 and the Wiring Diagram. Replace any previously removed wire wraps.

10.Close and secure the right side engine ser- vice access door.
