(1) Negative "−" lead (2) Body of the fuel shutoff solenoid (3) Plunger (4) Positive "+" lead (5) Electrical connector

This procedure tests the fuel shutoff solenoid for correct operation.

1. Remove the fuel shutoff solenoid from the engine. Refer to the Disassembly and Assembly Module, "Fuel Shutoff Solenoid - Remove and Install" topic.

2. Use a 12 volt battery as a power source. Connect the lead from battery positive terminal (4) to electrical connector (5) on the fuel shutoff solenoid. Connect the lead from battery negative terminal (1) to body (2) on the fuel shutoff solenoid.

   Plunger (3) on the fuel shutoff solenoid will extend the maximum distance when the leads are connected.

   If the plunger does not move or if the plunger does not extend the maximum distance, replace the fuel shutoff solenoid.

3. Use the 6V-7070 Digital Multimeter to measure the current through the fuel shutoff solenoid. Connect the battery, the fuel shutoff solenoid, and the leads of the multimeter in series.

   The current should be 1.0 ± 0.1 amperes. If the current is not within this tolerance, replace the fuel shutoff solenoid.

4. Install the fuel shutoff solenoid on the engine. Refer to the Disassembly and Assembly, "Fuel Shutoff Solenoid - Remove and Install" topic.
