2. Move the Forward/Reverse handle to REVERSE and listen for an audible click from the limit switch. If
there is no click, check the switch for proper alignment and switch arm movement.
3. If the switch is being activated but the buzzer does not function, place the red (+) probe of the multimeter
on one terminal and the black (–) probe on the other terminal of the limit switch. Without the lever
depressed, the reading should be no continuity. Depress the lever and the reading should be continuity.
If either reading is incorrect, replace limit switch (Figure 11-8, Page 11-10).
