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.
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 Warnings, Section 1, 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 rails just forward of each spring mount.
See WARNING “Lift only one
end...” in General Warnings, Section 1, Page 1-2.
2. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warnings, Section 1, Page 1-1.
3. Disconnect the three wires that are crimped together from the forward large post of the solenoid.
4. Using a multimeter set to 200k ohms, place the black (–) probe on one solenoid large post and place the
red (+) probe on the other large post. The reading should be no continuity.
5. Connect the three wires crimped together to the forward large solenoid post. Install washer and nut on
large solenoid post and tighten to 77 in-lb (8.7 N·m).
6. 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).

WARNING
• Keep people and equipment clear from rotating rear wheels. Do not allow persons under the
car. Contact with rotating rear wheels could result in serious personal injury.
7. 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.
