Test Procedures
at the MCOR. The reading should be zero (0) volts with the pedal up. Slowly press the accelerator pedal and
note the readings on the multimeter. As the pedal is pressed, the reading should increase until it reaches
approximately 4.65 volts when the pedal is fully pressed.
7. If reading does not increase as the pedal is pressed, check the drive bar for wear. If drive bar is not worn,
replace MCOR. See following NOTE.
NOTE: Observe closely to see if voltage randomly or sporadically fluctuates with pedal at rest, during pedal travel and
with pedal fully pressed. If it fluctuates, the MCOR is defective and must be replaced.
TEST PROCEDURE 13 – Motor Speed Sensor
See General Warnings on page 1-1.
Motor Speed Sensor Test without any Tool
CAUTION
• Perform the following procedure only on a level surface. To avoid injury or property damage, ensure
that the path of the vehicle is clear before pushing vehicle.
1. Place the Forward/Reverse switch in the REVERSE position to verify reverse buzzer is functioning properly. If
not, repair or replace the buzzer.
2. With Run/Tow switch in the RUN position, turn the key switch to the OFF position and place the Forward/Reverse
switch in the NEUTRAL position.
3. Slowly push the vehicle a short distance (about 3 feet (1 meter)). The reverse buzzer should sound and motor
braking should engage while the vehicle is rolling.
4. If the reverse buzzer does not sound and motor braking does not engage while the vehicle is rolling, replace
the Motor Speed Sensor.
Motor Speed Sensor Test with the CDT Handset
CAUTION
• Perform the following procedure only on a level surface. To avoid injury or property damage, ensure
that the path of the vehicle is clear before pushing vehicle.
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Connect the CDT to the vehicle. See Plugging the CDT into the Vehicle, Section 11, Page 11-2.
3. Access the Monitor menu and select SPEED PULSES by using the SCROLL DISPLAY buttons. The CDT should
indicate OFF when the vehicle is at rest.
4. While monitoring the CDT display screen, slowly push the vehicle a short distance (about 3 feet (1 meter)). The
CDT should indicate ON for speed sensor pulses while the wheels are in motion.
5. If the CDT does not indicate ON while the wheels are in motion, proceed to the following procedure.
Motor Speed Sensor Test without the CDT Handset
NOTE: The Motor Speed Sensor uses the 6-pin connector at controller.
Pins 4, 5, and 6 are the outputs and inputs to the controller and speed sensor.
Pin 4: Black/White Wire — Ground
Pin 5: Light Green Wire — Input to controller (0 to 5 volts)
Pin 6: Red Wire — Output from controller (15 volts to sensor)
