Typical example (1) Negative "-" lead (2) Body of the fuel shutoff solenoid (3) Plunger (4) Positive "+" lead (5) Electrical connectorThis procedure tests the fuel shutoff solenoid for correct operation.
Remove the fuel shutoff solenoid from the engine. Refer to the Disassembly and Assembly Module, "Fuel Shutoff Solenoid - Remove and Install" topic.
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 retract when the leads are connected.If the plunger does not move or if the plunger does not retract, replace the fuel shutoff solenoid.
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 15.8 amperes. If the current is not within this tolerance, replace the fuel shutoff solenoid.
Install the fuel shutoff solenoid on the engine. Refer to the Disassembly and Assembly, "Fuel Shutoff Solenoid - Remove and Install" topic.
