Testing the Fuel Stop Solenoid (In Place) (continued)
Testing the Fuel Stop Solenoid (Live)
Electrical System: Testing the Electrical Components
4. Use a digital multimeter, touch 1 test lead to the hold coil terminal and the
other test lead to the fuel stop solenoid frame (ground). The resistance of
the hold coil should be approximately 15 ohms.
5. Replace the fuel stop solenoid if the testing determines that it is damaged.
6. Connect the wire harness connector to the fuel stop solenoid.
1. Park the machine on a level surface, lower the cutting deck, set the parking
brake, shut off the engine, and remove the key from the key switch.
2. Locate the fuel stop solenoid on the engine and disconnect the wire harness
connector from the solenoid.
Note: The solenoid can be removed from the engine or tested in place.
3. If the solenoid is removed from the engine, ensure that the solenoid plunger
moves freely and is free of dirt, unwanted material, and corrosion.
Note: When testing the run solenoid, use test leads with at least 14 gauge
wire.
4. Connect a positive (+) test lead from a 12 VDC source to the pull coil and
hold coil terminals.
5. Touch a negative (-) test lead from the 12 VDC source to the fuel stop
solenoid frame (ground). The solenoid should engage, making an audible
click, and the plunger should retract.
6. Remove positive (+) voltage from the pull coil terminal. The solenoid should
stay engaged.
7. Remove positive (+) voltage from the hold coil terminal. The solenoid should
release.
8. Replace the fuel stop solenoid if the testing determines that it is damaged.
9. Connect the wire harness connector to the fuel stop solenoid.
