To test a neutral safety switch, first disconnect the battery. Then, remove the switch from the vehicle and use a multimeter to test it for continuity. If there is no continuity, the switch is faulty and needs to be replaced.

• Open the hood and locate the neutral safety switch on the transmission
• Disconnect the wiring harness from the switch
• Use a multimeter to test for continuity between the two terminals on the switch
• There should be continuity when the switch is in the “run” position, and no continuity when in the “start” position
• If there is no continuity in either position, replace the neutral safety switch
