3.
Move the accelerator pedal and listen for an audible click from the switch. If there is no click, check the limit
switch for proper alignment and switch arm movement.
4.
Place the red (+) probe of the multimeter on one terminal and the black (–) probe on the other terminal of the
switch. With the accelerator pedal fully released, the reading should be no continuity.
5.
Apply the accelerator pedal to activate the switch. The multimeter should indicate continuity when the switch
lever is activated. If either reading is incorrect, replace the switch.

3.
Set the multimeter to 200 ohms.
4.
Measure the resistance between the two wires at the two-pin connector (front drive gearcase side).
5.
The resistance should be 24.7 to 27.3 ohms.
6.
If the resistance is not within the stated range, replace the large output cover sub-assembly.
