6. Reconnect the three-pin connector at the motor speed sensor. Using a multimeter set to 20 volts DC,
place the black (–) probe on the battery no. 4 negative post and place the red (+) probe (with insulation-
piercing probe) on the green wire between the three-pin connector and the motor speed sensor.
6.1. Raise one rear wheel off ground. Slowly turn the rear wheel to rotate the motor armature. As the
armature rotates, the voltage reading should alternate from zero to approximately 4.85 volts. The
voltage reading will fluctuate from zero to 4.85 volts and back to zero four times for each revolution
of the motor armature.
See following NOTE.
NOTE: The voltage reading of 4.85 is an approximate reading. The actual reading may vary from 4.50 to
5.00 volts.
6.2. Replace the speed sensor if
• there is no voltage reading.
• the voltage reading is not above 3.50.
• the voltage reading does not fluctuate as the motor is turned.
TEST PROCEDURE 14 – SOLENOID CONTINUITY
See General Warning on page 1-1.
1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position
jack stands under the frame crossmember between the spring mount and side stringer, just forward of
each rear wheel.
See WARNING “Lift only one end...” in General Warning on page 1-1.
2. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-1.
3. Disconnect the yellow wire from the large post of the solenoid.
4. Disconnect the resistor terminal from the same large post as the removed wire.
5. Set a multimeter to 200k ohms. Place the black (–) probe on the solenoid large post with the 6-gauge yel-
low wire and place the red (+) probe on the large post with the 6-gauge red wire. The reading should be
no continuity.
6. Connect the 6-gauge yellow wire and resistor to the large solenoid post. Install washer and nut on large
solenoid post and tighten to 77 in-lb (8.7 N·m).
7. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first.
Tighten battery terminals to 110 in-lb (12.4 N·m).
8. Place the Tow/Run switch in the RUN position, turn the key switch to the ON position, place the Forward/
Reverse rocker switch in the FORWARD position, and press the accelerator pedal. The solenoid should
click and the multimeter should indicate continuity. If the reading is no continuity, replace the solenoid.
TEST PROCEDURE 15 – FORWARD/REVERSE ROCKER SWITCH
See General Warning on page 1-1.
Forward/Reverse Rocker Switch Test with the Diagnostic Handset
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Connect the handset to the vehicle. See Plugging the Handset into the Vehicle on page 22-1.
3. Test FORWARD INPUT.
3.1. Access the Test menu and select FORWARD INPUT by using the SCROLL DISPLAY buttons. The
handset should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or REVERSE
position.
