1. Disconnect the black/yellow lanyard stop switch wire from the brown engine harness wire.
2. Disconnect the black stop button wire from the black engine harness wire.
3. Set the DMT 2004 Digital Multimeter to read ohms on the auto scale.
4. Ensure the lanyard stop switch is in the "RUN" position.
5. Connect the DMT 2004 Digital Multimeter to the black stop button wire, and the black/yellow lanyard stop switch wire. The
meter should show no continuity. If continuity is found, the lanyard stop switch, and the stop button must be tested
separately to determine which component is defective.
6. Set the lanyard stop switch to the "OFF" position. The meter should show continuity. If no continuity is found, the lanyard
stop switch is defective and must be replaced.
